I guess, control point weight information to newly created ones could be 
carried through CustomData. Surface grid and curve leg structure can be 
reconstructed by following newly created edges.

There is another problem in these two modifiers. Vertex merging can 
violate lattice structure, these cases might be tricky to handle. In 
worst case maybe it's possible to end up the error message.
