Just thinking at the moment ...
I have one of those lying in front of me ...

Which can be made compatible to classic GUS cards according to gerwin's post here by adding 512kb of RAM in the intended solder footprint.
EC251 InterWave Audio Card
Might also be possible to easily boost it to 1MB.
AM78C201 & IW78C21M1 chips can still be bought as NOS from China.
Seeing how above card is a 2 layer board, it could be produced cheaply as well (~$20).
Considering GUS cards go for quite a bit these days ($80+ last time I checked) it might be possible for one to solder one's own card for maybe $30 (assuming the custom chips don't cost an arm and a leg from china).
As usual with my projects, I'd reverse the schematic, draw an example PCB layout and produce a prototype and release the files once the design is confirmed as working (I _hate_ distributing stuff) so basically anyone with soldering experience and patience to go through acquiring all parts could build his own card.
What's you guys' and gals' opinion on that?
EDIT: development blog here: Newly made Gravis Ultrasound compatible cards ... what's the degree of interest?
Current Project: new GUS PnP compatible soundcard
