You could switch the every-other-scanline and every-8-scanline sections depending on when you need to draw what. In that case you would need to hang a label on the every-other-line section and BNE to that rather than EndOfLine. I'm sure there's a more efficient way to do this, but this is the obvious way to me. (Well, except I'd do it as a DEC loop rather than an INC/CMP loop, as you imagined, cutting like 5 cycles out of the 68 or however many you have to spend on a line.)
