Your idea would not allow each table to sound it's best due to compromises in design necessary for it to work, but even if it were practical, it would be more work for only two decks than simply building two plinths. i.e., if you had ten TT's to plinth, maybe (though I wouldn't), but for two, why bother?
Not to be unkind, but this seems like one of those ideas that might deserve a moment or two of internal dialogue, and then immediately dropped.
