Actually this experiment has been done succesfully before,by White Wolf with Exalted and it works. You remove the min/max by making everyone over powered, this forcing the munchkins to roleplay because all of the things that normally occupy their megalomainc little minds have already been given to them.
Also works with White Wolf's "Scion" series of games. But yea, it does remove what the munchkins would normally do, because Space Marines are all powerful, and you can't really get "more powerful". More skilled, sure, but never to an extent that they're "overpowered" compared to the rest of the group.
