I think they've got the 110's at least as zipped up as they can, but you're right, it would be a huge mistake to do a cold turkey cut-over, especially with their history.
I think the best route would be to make a special version of the SEUC as the test mule on a limited run, say a few hundred to 1,000 units max. Give those early adopters carte-blanch, with extended warranties and free loaners, in the event things go south. I'd rather see that, then them try this on a larger scale where they can't afford to keep the peasants happy. This way, with a controlled limited scale launch, they can keep close tabs and quickly react to the normal bugs and get them ironed out. Imho, this would be a big step, and with a little caution, could help them competitively in a big way going forward.
