adaptive engine mount retrofit
Just an odd idea. It seems that 964/993/996/997/991 engine mounts are all physically interchangeable? If so, PDEM dynamic/active hydraulic engine mounts from the new models would bolt on. Question is if it could be wired up for a simple on/off operation? Or even 0%/50%/100% modes? The mounts appear to use a 3-pin connector, which would make a +12v/gnd/signal (0-5v?) input seem likely.
Bringing this up after an 1800 mile holiday road trip with wevo mounts- great for "sporting" but certainly introduce needless NVH for highway cruising. Of course, the pdem mounts would be less actively intelligent without a pasm to talk to but still seems like a worthwhile prospect.

Ok..You have my attention

Confirming your first assumption is the first step.
the second would be understand how do mounts work

Check these links out, explains the inner workings. Looks like you could just energize the magnet with 12v to engage the solid engine mount performance and deeneegize to get the viscous mount performance.

If the input signal is a variable 0-5v, then you could certainly build a stand-alone controller using whatever accelerometer/etc inputs that you want to make it smart. But that’s getting way ahead of the game.
I’m going to stop by a local p-car speed shop soon for some other work. I’ll see if they have an old 997/991 mount lying around that I can borrow to check if it physically fits. Maybe they’ll know how the pdem mount inputs work. I haven’t seen any technical literature on the system, only watered down sales ads.
Sounds like I’m not the only crazy person who would find this useful. For some perspective, the mounts are over $2k/pair from Porsche or about half that if you can find them used.

When these first came out I looked into this and decided there were too many missing sensor signals that I would need to supply over a CANbus for the controller to function properly. I think I found the documentation describing what you need in the workshop manuals.
