I do see your points, and agree with a lot of your logic having taught grounded ensembles where the kids bounced from instrument to instrument.
However, honestly, as a former batter player, half of the appeal was being able to be out there as part of line. It takes serious skill to clean a 7-10 person snare line, especially with todays drill. same with a 4-6 person tenor line.
sometimes change for the sake of change is not a good thing.
and, IMO, percussively, the domed stuff I have seen makes electronics an even bigger mess balance wise
