So far I just had a quick glance at your post. But just some quick remarks with respect to the technical side of counting votes:
I'm afraid that's very dificult, if possible at all, to realize using our current voting process. And personally, I do not want to complicate things even more. We already had a very hard time the last time to come with the solution as it exists now.

This on the other hand is very simple and does not need any change to the voting process. Simply skip the ones that already got a price and choose the next one in line according to the ranking determined using our voting process as explained in the Wiki.

Edit: Please excuse me if I am too picky about this but I learned from the last time that a voting process is indeed a very delicate topic and even the smallest details could lead to lots of confusion, trouble, changes in the results and what not.
