i'd say no.  GC isn't a panacea, nor an automatic resource management.

if you really want it to help, i'd say go with Jerome's suggestion,
and store the whole C++ object in the Lua-allocated full userdata.  Of
course, that helps only if it's a really heavy object, and not a
complex weave of interrelated things.  (unless you manage to store
them all in one or several Lua objects).
