What wasn't "reliable" about your well tempered? Don't see any way you can combine the two. If you like the clearaudio better, then I would suggest you sell the well tempered and get an isolation base like a Townshend seismic sink or Ginko.
My best suggestion would be to get the Well Tempered operating properly as I believe it is the superior table.
