R' B2 L //EO (3/3)
(F' U) //Simplify (2/5)
B2 U2 //Setup (2/7)
D B' D //DR (3/10)
U2 F2 L2 F' L2 F2 * L2 F L2 B //2e2e (10/20)
* = F2 U2 F2 L2 U2 F2 U2 L2 (8-4/24)

IF gets 23 by inserting a 2e2e (6-3) and a 3e (6-6).

I also had this shorter 2e2e, but I couldn't find good insertions:
U2 F2 L2 F L2 B' U2 B2 F' //2e2e in 19, hopefully shortened by 1 after insertion
