I don't think so. He did attempt 3F+3Lo, though.
As far as I know, the only guys who were trying 3A+3Lo were Hollander, Denommee, and Abt. The Abt example linked above looked pretty good, maybe 0 GOE.
Like subtlety in ice dancing
Blades of Passion, I forgot to say that I LOVE your idea of having wildcard element slots in the FS (and less required elements). It's needed to put more of the free back in free skate, and would encourage a wider variety of programs and skaters to succeed. In fact I wager that some form of this will inevitably happen in the COP. The choreographed step and spiral sequence without level requirements is a step in that direction. I'd also wager that sooner or later jump combinations will get a bonus. I just wish all this could happen sooner because skaters and fans deserve those improvements now.
