Whats that noisr you make whe you see someone getting really baddly hurt on a youtube vid?.... Gruwhuhhh! Nasty business.
Anyway, regards the BL motor idea, I believe there is a company producing AC induction motors that dont use permanent magnets, but at the moment they havent made anything small enough or suitable for RC use.
Im interested in the new engine design idea- if that works out you wont have to worry about working much I imagine
Oh, and just to add insult to injury, have you seen this Drknow?

I know, I know, Im an evil bar-steward. I wish you a speedy and full recovery man, I would hate to loose any use of my hands, and someone who relies on them for work (like you do) would miss them even more. Get well soon.
