Yes, I tried to make this possible.

I am wondering whether there are some other impacts that I have not

The heap object types will conflict, for one.

Each compiled library will have allocated the identifiers separately and
they probably won't match structurally. It's not quite as simple as just
combining the tables, either, as the generated program creates heap objects
with the appropriate type id as an immediate constant.

Work-around-able with some indirection, I suppose.

You would also need to combine the lists of heap roots.

All doable, just some work.
