Maybe, you can make a devilite a rare monster, like it should be called a successful devilite, i did some wiki research and read that some broke from the ranks to start a small business (http://wiki.spiralknights.com/Devilite). maybe you can meet one of them in the clockworks, it should look like the normal purple one except it wears a business suit and a briefcase,(it would still attack you) it will drop the following: all the normal devilite drops, just an increase chance,2 gold coins( hes successful! ), the business suit costume; it just a plain business suit, and the suitcase; a trinket which gives you an extra 50 ME supply, (mist tanks still only give you 100me, not 150).
any thoughts?
I only support the business suit and gold coins idea, the ME trinket just seems,... wrong.
other than that, great!
