Hmm, no, there's no way of doing that currently.

The "normal" workflow to do that is to just have two files/buffers, one
with the module, the other, as you say, requiring it.  And then you
re-evaluate things in the module's buffer first (with C-c C-k, C-c C-e,
etc.), and those redefinitions should be visible in the other buffer
without restarting racket.

HTH,
