If you think it's perfect for the figure, draft it! Then, finish your current stuff, and in the meantime buy up some figs/resources, and come back to it after the other stuff's done.
I'm trying to write jokes, so I'll inevitably think of ones while I'm trying to sleep, not get up to write 'em down, and completely forget 'em later on. That's the only reason to even THINK I know what I'm talking about
Of course, then there's the Mitch Hedberg school of thought: "I sit at my hotel at night, I think of something that's funny, then I go get a pen and I write it down. Or if the pen's too far away, I have to convince myself that what I thought of ain't funny."
Back on topic: if you look at the draft tomorrow and think, "What was I thinking?" then just pitch it.
No harm, no foul.
Good luck, man!

Holy crap! There were five troop builders in 1985 - what am I getting myself into!?!
