Stoppers: I've no idea about the amount of work, but I think you're right on all the other points. I can't see an alternative to doing something at least vaguely along those lines. The current situation can only lead to the death of RISC OS. Can anyone see a way of bringing new or returning users in any number to a desktop machine running on current ARM hardware? If you want to stick to ARM then the possible survival route would be via portable devices (and since the rest of the hardware's still totally different, that's probably a hard job too), where there isn't the competition from other hardware that's an order of magnitude faster and cheaper.
