That's really a Swig issue, not a Lua one.

I suspect it's possible -- much of Swig's Lua-C interface is
table-driven, particularly data access and type-checking.

I'd look at the C code generated by Swig (it's fairly repetitive, and
not hard to understand).  E.g., look at how it implements the __index
metatable operation for Swig userdata.
