That should do quite well - i.e. a somewhat large chicken wire/fence
spread out beneath the coil. I've been doing this on some demo stands,
chicken wire over a concrete floor, and it works quite well. Fence size 
being something like 2m x 2m, and using a broad copper strip or RF braid 
to connect the TC sec base to the fence.

Just take precautions that you don't actually stand on that fence while
doing TC stunts... :-) Especially if you have the NST center tap connected
to the fence instead of mains ground (some people do this, though I don't
know why, really).

cheers,
