Horrible scramble. No 4 movers. Mallard doesn't even give a solution with linear 5 movers and rzp in 5, dr in 12.

Optimal from DR

Horrible scramble that looked decent. Lots of 4 move EOs but the only sub12 DR with semidecent subset I found was:
(L D) B' D
R , U2 R2 F L2 B L //DR 4c3 in 11 
But this is horrible. 14 optimal and all 14 move solutions are absolutely horrible to find.

Mallard with EO 4, rzp 5 gives 25 from that DR
Mallard with EO5, rzp 5 only gives 24 as well :D

Kind of a doomed scramble but happened to stumble upon the right DR.
Only 1 4 move EO (2+2 NISS ofcourse :D ). Only 32 5 move EOs all together and 16 linear 5 movers. 
Such a bad scramble that I started NISSing rzp in 6 and got lucky.

The L' B2 L version of the DR is 22 optimal but I didn't have time to check that since I spent a lot of time with this 2c4 in 9 that seems to have a pretty hard to find 14 as optimal:
