I believe it can help. My idea is all resonance shocks from headphone jack plugging, volume knob or tapping are passed to tube through tube legs.
I would not desolder but using plier simply cut legs and solder kind of flexible wire, Rest of legs (on PSB side and tube side) I would damp with dynamat stripes.
I'm in about legs. plugging in headphone just impacts whole the device so hard that tube filament gets noisy and all (or most) of the vibration passes through the tube pins. if it was not about legs, the noise would appear in an intentional hand shaking the amp just like when you shake matchbox. I think Schiit could solve this issue by doing these three simple changes:
1- these pencil-sized mini tubes benefit too much of elastic rubber rings. I would add two or three rings which IMO decreases the microphonics at least 30-40%
2- tubes would do alot better if pins were soldered using very flexible multi-strand thin wires not that stiff and hard single conductor pins
3- they could contrive tubes on a very gentle metal springs based on the PCB as tubes could easily move within a range so they were in a suspension position most of the time
I think these mods will cancel the noise at least 80% and maybe more, one should get the show on the road
