I'm actually of the mind that something like that would be fun, but in a different way than you're picturing it. When we finally get a community server going I'd love to have a set of shards mirroring our original servers (Virtue, Freedom, Victory, Justice, etc.) and perhaps an extra shard (Ascended mayhap?) where dev tools are enabled/restrictions are disabled so that people can create a character using any mix of powersets for fun. Like a Tanker with a Psi blast primary and a Demon Summoning secondary, so he'd be like a very resiliant blaster with pets, and perhaps even the ability to choose which version of an epic/patron pool you'd like to have, so you don't get stuck with a power selection you don't like due to archetype. That way controllers could get Soul Storm from Soul Mastery, or scrappers could get all the shark effect powers from Leviathan Mastery instead of waterspout and the others. I think it'd make a nice addition to the regular game so we can play it as it was/was meant to be, and a just for fun server where we can make those heroes that we always secretly wanted. Don't lie, you know you always wanted to have an ice armor scrapper, or a spines tank. XD
