Once again I believe the simplest answer is to just share the inventories; people who want a fresh start are welcomed to do so but people who don't want a restart aren't forced to do so.
..Also I thought this was cleared up, didn't realize we were still looking for solutions..
**Edit**
And also, by the time the inventories would be shared again people would have already regained their previous items and whatnot; therefore the sharing would be near pointless, except for maybe bringing over mementos or something of the sort. And I don't exactly see why people should be on an "even keel" so to speak, as I don't think there's any problem with people being stronger than others.
