It probably will just make your life more difficult, the bees will be fine. You have a frame or two that wasn't touching the others and they built the comb out into the beespace. It would be good if you could go in find these combs and trim them back, then add the 10th.
Yes it will be a pain, yes it will be a mess, yes you may ruin some brood, but in the long run you'll be able to pull the frames out for future inspections. The idea is to keep things workable.
If they get upset on ya just correct their attitudes with a lil extra smoke, don't let them talk back to ya and get the upper hand!! Discipline, and tough love!!! ;) :-D ;)
