Two items.

Nick, could you explain why the restart is a problem?  The time GDB
takes to reject an interpreter doesn't seem too bad.  I don't want to
optimize the wrong thing.

Bob, since we last discussed this the interpreter commands have matured
a bit.  There's even tab completion for the CLI interpreter-exec
command; try "interpreter-exec <tab>" and you'll get a list.

Would -interpreter-list and -interpreter-set do it for you?

I thought there already was a "set interp", but it seems I was
mistaken.
