I am on 17 of 29 trays and my front top teeth are now slanting outwards in a way I hate. Should Invisalign do this?

The orthodontist showed me the final result (tray 29) on the computer. The top teeth will slant outwards even more than now in order to make room for a tooth that isn`t in line with the others. It looks unnatural and is now making my overbite worse. If I get to tray 29 and I hate the result, is it possible to use the trays in reverse order until tray 13 or so (when the front teeth weren`t flaring so badly). Unfortunately my ortho gets angry when patients voice such concerns.
