This is exactly how the current wave of gerrymandering began. The mandate to create "majority-minority" districts led to the concentration of districts that favored minorities (Democrats) but at the same time created two or three districts with sizable (but not insanely so) Republican districts.

From the Atlantic:

"But just in time for the redistricting in 1990, some enterprising Republicans began noticing a rather curious fact: The drawing of majority-minority districts not only elected more minorities, it also had the effect of bleeding minority voters out of all the surrounding districts. Given that minority voters were the most reliably Democratic voters, that made all of the neighboring districts more Republican. The black, Latino, and Asian representatives mostly were replacing white Democrats, and the increase in minority representation was coming at the expense of electing fewer Democrats. "
