Why? They aren't from different times; they could never exist simultaneously like a future version of the character brought back to the present.

Shadow Knight is an alternate version of Bart from another dimension (a mid evil game)

So if Robo Burns & Doggy Smithers can be separate characters (and these should be skins more than separate characters), then Shadow Knight should be also.
