I made a 2x2x1 while preserving a piece for the 2x2x2 by doing the B2 at the start preserved an f2l pair while making one with my preservation move swapped them in their correct locations. After that I ignored the last f2l pair to see if I got something good so I did an oll and got lucky with a last 3 edges solved by a u perm.

Yellow X-cross to easy first F2L pair, My kinda bad setup to F2L pair 2, but it works out nicely with an extra setup And do a double move insert to get to an easy OLL and PLL.
