New base - multi printer - harmonics - over thinking?

I have the X1-C sitting next to my Prusa on what I thought was a sturdy table but I see the PTFE tubing on the Prusa flapping about.
My daughter has now ordered a P1P so time to relocate everything to a better enclosed desk to keep the heat in and dust out for the P* units.

BUT I saw a YouTube clip where the guy thought the unit was going to damage his wobbly desk so he put a tripod under the table mid print, the unit stopped with a notification that the harmonics had changed.

Yes finally the actual question…
If the Bambu does real-time harmonics checking and I sit a P1P and the Prusa next to it, will X1 or P1 get the wrong vibes from the others printing?

Secondary question being, any suggestions for design and materials?

Thanks.

Perhaps use two smaller tables instead of one large one?

Yes, I think that will be the plan.
Solid macrocarpa 200mm x 100mm sleepers, low to the ground to minimise shake then enclose in an external frame for dust and cool breezes for the Prusa and P1P
