This has a findable 22 from +7 to htr on inverse, but I didn't have enough time to check all variations.

Of course the best looking dr I wrote down had a 20 that doesn't come from a linear htr:
L' B R B U2 L U' L U2 L //4A2 4E
Tunnel visioned a bit too hard on the R B2 R variation, which had linear htr in +5 but no good continuation.

Only other promising dr:

this gives S slice in 20, which has horrendous slice insertion
