only if you can convert the .sf2 file to a .dls file and rename it to gm.dls, otherwise no. a SF2 soundfont is different from a DLS one.
Then maybe we could rewrite in wine's dsound/dmusic routines responsible for playing MIDI so it would use soundfonts instead of dls file?
After all it's all just backend - games and midi apps won't care if the API (function names and parameters) would be same
