I think that's a mistake for the reasons I posted above. This is especially the case if you don't want to spend a lot of time and money trying to engineer something that really is asking for trouble if you get it wrong.
To distribute the loads, you'd need to futz around with the "natural" line of dodger. I once saw a dodger bent and ripped-up when a jib whipped the lines across it from a retro-fitted mid-sheet boom location.
A broken boom -- or broken boom fittings are really no fun. A broken boom can be very dangerous, too.
I think that going with a lot more efficient, less expensive, and functionally superior (for your boat) end sheeted boom is the way to go. If you're trying to find a re-cycled boom and re-purpose it for your boat; or even if you spring for a new one, you'll be a lot happier.
