Tempting, but the this is the "swapping bits" that I was referring to. The solution skips these three combinations:

If you look at them closely, you'll see why you can't generate them. That's what got me stuck on this track. If that can be solved, this is a good way to go.

Oh, and since you mentioned this was untested, I won't comment about for my $bit ($splits-1..0) { :)
