I'm wondering, given the very talented developers working on DOS box, if you could possibly make an operating system that can distinguish between midi playback in an MS-DOS game that is General Midi versus playback that is for an LA synthesis module?

Not really, as all it is, is MIDI data being sent to a MPU401 interface.

The best one could do is assume a game using the intelligent mode of the MPU interface needs LA synthesis... but not all games that were written for LA synthesis use intelligent mode.

I suppose the question is - is it possible to distinguish between the target MIDI device for MIDI messages being issued by a game [and preferably when the game starts]?

You might be able to pickup SySex data, but not all LA games use that and just stick with the default instruments either.

But considering one has to configure the sound card options anyway, I'm not sure about a need for such a detection.

Indeed - what use would it be to detect the target MIDI device anyway
