Those two things delay a quality implementation of 2-sided printing.

But if you just want a quick 'n' dirty solution, let me know. I could roll that out now. I can make it so that cards are always arranged as if you're printing 2-sided. (As you say, inverting the > shaped layout of the cards to a < shape on even pages). If printing 2-sided, that's the layout you need, and if printing 1-sided it doesn't matter. For this solution, you would manually have to make every third card be the appropriate card back. Annoying but doable. For example, add cards to print in this order: Batman (comic), Spiderman (comic), Fat Ninja (comic), Batman (mini), Spiderman (mini), Fat Ninja (mini). Tell your printer to print 2-sided and you're done.

Related to two-sided prints, I also plan to steal borrow i_r_beej's neat 2-sided printing idea. While it uses more paper, it allows for always-lined-up two-sided cards AND helps cope with paper thickness issues. It does those things in theory, at least--I haven't tried it out yet.

If some (ahem) custom project had card backs that were oversized to allow for printer mismatch, then the quick and dirty solution would probably work.
