And I find your solution even stranger. Why hasn't the bad guy found this mirror and made better use of it?
Maybe because the BBEG didn't
build the dungeon; he's just the one who's living there now. The mirror might be in a secret room he's never found.
(As a side note: I lived in an apartment for three years in my college days, and found out about a veritable 'secret compartment' previous tenants had made to hide drugs three days before I moved out. How do I know they used it to hide drugs? There was still a small plastic bag of marijuana in it.)

Who made the mirror? How many other folks has it found?
If it's a one-shot plot device, this info is irrelevant.

What happens if the party fully maps the dungeon and encounter the mirror?
Possibly the 'switched' PC was whisked away by another BBEG (the original builder of the dungeon, maybe?), and the mirror needs both 'switched' parties to reverse the effect. Until then, it's just a mirror.
Conversely, what happens if the 'stealth guy' that got 'switched in' deliberately keeps them from finding it?

What if my campaign doesn't have this alternate dimension from which his equivalent can be from?
Alternate dimensions aren't necessary. It can switch him with some kind of critter from the Nine Hells, or a something the original builder planted there to mess with anybody who ever found the mirror. There can be any number of explanations as to what happened to the 'switched' character.
Again, a converse question: What if
my campaign doesn't have dopplegangers to switch with him before he enters the dungeon?

Why didn't my 75 on a Gather Information roll not find Bard's tales about this strange mirror in the dungeon?
A.) You rolled a
75 on a Gather Information check? [
Looks at d20] Ya must have a helluva modifier.
B.) Maybe because the Bard's tales never mentioned the mirror, because the bards who composed said tales didn't know about it.
Point is: Old Drew Id's idea about a 'mirror' switching the character after he enters the dungeon is no more or less plausible than your suggestion that the 'switch' happened before entering the dungeon. It's a game; moreover, it's a game where odd stuff happens with great regularity. Sometimes you just have ta wing it.
