Let's see...

You could put a setscrew through the wheel hub (and into the shaft a little bit).
You could make the hex shaft just enough longer to put a groove for a snap ring on the outside end.
There are probably a couple other ideas for someone to come up with/suggest.

Pretty much, all you'd need to do with the wheel is keep it from sliding off the end of the shaft. A press fit would also help, but could make quick changes a pain if that issue ever came up.
