Target wall shelves are OK, we sold many TT2's, but the laminated shelf material itself Target choose was never great/not the most musical, the frame is good though, welded well, not the most lightweight but it's rigid, well "was" good as the new Target stuff -reacquired by some Canadian Co.- is an absolute joke unless your handy at welding yourself to fix all the mistakes/bad welds, we had simple 1/4" cheap and dense particle board cut to size and painted black, a $30 option as an alternative to what came with the Target TT-2, sounded more musical, I used one myself for many years upstairs before I moved my system to the main floor which is on a solid cement foundation, Much better.. Many other customers learn to walk carefully when the deck is playing using the AudioTech or Archidee as I mentioned before, but I understand this can be simply unacceptable in many cases. Just don't want to see you doing a disservice to your new deck evaluation with questionable mods probably actually working against it IMO, in your situation I would take all that stuff from under the deck and simply place the deck on the Target shelf alone as a start, this way you're hearing more the deck and less of the shelf mods.
We tried swapping out the Target MDF board for the MDF board off an old Sound Org table - no difference to my cloth ears. We tried tempered glass and laminated (ignoring generalised prejudice) in place of the MDF, and it was at least as bad as 'conventional wisdom' suggested. On the other hand, a wooden chopping block and a c.6kg slab of granite were expected to be bad (rigid but not light) - the wood sounded a bit dead but the granite was not bad at all.
I am not sure why you regard what is under the LP12 now (SRM platform) as 'all these questionable mods' or '' all that stuff'. Mr. Swain is ultra-knowledgeable and ultra-helpful, but not known for being undeservedly kind about tweaks and 3rd party products he does not use/ offer. Equally, Infidelity sell the Tangerine products and not SRM, but fitted the SRM base and platform to my old LP12 at my request and reported that they too found it worked well (they tested on a Quadraspire wall shelf at the shop, not my Target).
However, none of that proves that the SRM platform will be a help rather than a hindrance with the Stiletto. As mentioned above, we will certainly listen with & without to hear whether it is a plus or a minus - once we have sorted out other things that clearly do need changing. After all, critical listening while still having a hum and while using RCA-BNC adaptors is clearly pointless. In the absence of a complete analysis of everything that is going on when playing an LP in my house (which we certainly do cannot have), using ears to decide what works in this specific situation seems the best approach.
Your comments on Trampolins and no-baseboard LP12s match my memory. I found taking the hardboard off my old LP12 a modest improvement, but every time I heard a Trampolin on a wall shelf (or an Ikea table on a concrete floor) I found it took some life and vigour. To me, that's not a surprise, because my understanding is that the only reason Linn created them is because so many people put LP12s on non-ideal supports (including hefty racks full of boxes).
I also note that the Linn feet on my old LP12 are (still) rubbery and compliant, and of course the Tramp has much more of that. The SRM base and its metal feet are less compliant than the standard feet. Thus, if the argument about two sets of suspension in motion are right, and if one has a support/ room that can live with no bounce/ absorption at all, then bases from SRM/ Stack/ Tangerine should all have an advantage. Equally, if the Tramp 2 really does work on a heavy support much better than a naked/ solid base (which is the point of its existence) then I can well imagine that those same bases might be much less appealing than a Tramp 2 on some supports.
On the other hand, I am wary of judging today's Linn standard base or Tramp 2 for a particular room & support unless hearing that combination. If I were using the top of a big Quadraspire rack to test LP12 bases (or a sideboard), I am very willing to believe that my ears would have agreed with other people and favoured a Tramp 2. The fact that the Tramp 1 was not great when launched, with many favouring no base or the hardboard if on a 'light and rigid support', does not mean I can fairly judge how today's Tramp 2 would sound on a different support in a specific room using the evidence (i.e. my memory) of more primitive kit from 30+ years ago. If I really want an answer in 2022 any actual room, then listening is surely the least-bad way to get one.
