I would sincerely appreciate it if you took a look at your champion switch function. I've been in far too many games where people have tried to trade champions, but were unable to and were stuck with screwed up runes/masteries.
One other suggestion: make switching possible as soon as both parties are locked (i.e. 1st pick and 3rd pick are locked, now they can trade)
