Doubles challenge mode

Would it be possible to add challenge mode that turns all single battles into double battles? I’ve been looking for a pokemon game that focuses on single battles for a long time with no avail, and I wonder if Pokemon Insurgence could become one through challenge mode.

Pokemon Sweets is pretty much based off double battles. So you could try that out.

Yea, I’ve heard of it but flavour-based pokemon types (as well as sprites and map design) is big turn-off for me.
