[Harry Potter/Doctor Strange] Could a Muggle who was sufficently trained in the mystic arts be able to successfully infiltrate the Wizard community and be accepted as one of their own?

I think it would depend on how well he knows the Wizarding world. Based on what I've seen about Strange (nothing but the movie), it looks like much of the work is done with hand motions and poses whereas in Potter, it's all wand work. He'd have to figure out a way to incorporate the wand into his repertoire. 

He'd also have to be familiar with the culture of it: stuff like Diagon Alley, Hogsmeade, etc.

But given how insular the various wizarding communities seem to be (Goblet of Fire made a big deal about how rare it is for wizards of different countries to interact), he may be able to just pass off any eccentricities he has as a result of him being from another country. Strange's world is much more violent though - conflict happens in the Wizarding world through duels of spells whereas in Strange, you generate your own weapons and deal a lot with altering perceptions and realities. A Doctor Strange-type magic user would have to be careful to restrain himself so as to not arouse extra attention.
