Well this changes things a bit maybe, huh?
Not that I have any clue what that means for Oopsy~
Many differences from Gen export, at least at the moment.
I did, however, fire off a VST3 plugin with a junk UI in 3 minutes.
Going to answer my own question here: it may be possible but not at the moment without manually tweaking the C++ code.
