I actually was faced with this decision to use LKali with my DQXQ for Z since so many of the PADX builds suggested them. I decided to use double DQXQ instead, and lo and behold the opening board had two light orbs. Very nearly dodged a bullet.
I did it using Fafnir and Chaore's Verdandi. All the other Verdandi's I have aren't skilled
I would go GGY, but 99% gravity followed by an 10/11k preemptive is not something I want to deal with.
Also, I died on Wadatsumi three times. The time, I fucked up matches and died on the first floor. The 2nd time, I failed to kill UmiYama and used the big move. 3rd time I tried to chip him down and sky falls made so that he fell in range to use the big move.
