Switching rulesets in the skin editor?

I think it would be nice to be able to switch rulesets in the skin editor directly, or atleast let it use converted maps.
The reason i think this is usefull is that everytime you make a change to your skin for a specific ruleset, you have to switch the song in the song select, but it also has to be a map dedicated to the ruleset.

Its not that time consuming but i think letting switch this in the editor directly is going to be faster and more comfortable.
I think that letting the editor load up converted maps would be the best option. The map only has to be reloaded in a different, the same song is going to play, which i feel that this is what the user expects. otherwise you can just make the editor choose a random map from the specific ruleset.
