Subset are probably possible. Full implementations, probably

I think CLR and Parrot already solves the multiple scripting
language problem in a more practical way. After fixing up the Lua
VM to implement various languages efficiently, you'd probably end
up with something like CLR or Parrot. So, why reinvent the wheel?
Something with Lua VM is probably better for language subsets, so
for general interpretation of language sources, it won't fit the bill.
