I think it could work as well, at least to semi-frequently solve parity with a 4-cycle. Solving all corners 4style would take a lot of algs.

The cool thing is that you can also influence how often you get these with cycle breaks. Let's say I want to use U+Sune, then I need the consecutive targets UBR->LUB->LUF somewhere during the solve. If the first target in a 3-cycle is UBR and then there's a cycle break (not too rare), I can select LUF as the next target, then there's at least 4/15 chance that the next target can be set up to form a 4 cycle with a D-face move + L' (LDF, FDR, RDB, BDL). Another case: first target is RDB, then a cycle break. If the sticker in UBR is blue (my left face), I pick that next and can set up the 4-cycle with L-face move+B. Or, if I have a cycle UBR to anywhere on the L face, then a cycle break, I can pick the next target clockwise from the second target on the L face for a 1 move setup, assuming that corner isn't solved yet.

So if you learn a handful of 4-cycle algs, which cases they can cover with easy 1-2 move setups, and the optimal cycle breaks to maximize occurrence, you should be able to use one quite frequently in solves.
