Yeah, that would be awesome.
I would love to see the dancing bear!
Totally missed opportunity.
Missed opportunity yes but I imagine it would just make noi sense why sinerian guy is a werebear. Not enough people in the audience would get the context.
Now if in
Sonic 3 we get to see GUNs aircraft carrier (or at least the movie-adaption of
Metal Harbor), I can imagine the fighter pilots taking off to the
AfterBurner theme. If they want to they can have
Cmdr. Walters talking to one of the fighter pilots under the callsign "AfterBurner" and if Paramount wanted to they could give Tom Cruise the role as a cameo.
That way even if fans in the audience don't get AfterBurner as a reference they will get Top Gun as a reference. And given Sonic's third movie will be a loose adaption of Sonic Adventure 2 means GUN will be more involved for such a reference to happen.

But making some random Siberian dude a werebear for no reason, I can see why that would never happen in a Sonic movie without context.
