It sounds like this should work great.  Good luck.  For those who may be 
looking for materials, several folks have said they buy the white 1/2" thick 
HDPE cutting boards and cut them up for primary supports.  My wife has one 
that looks like it would work great.  I wouldn't think they cost more than 
about $10.00.
