Don't get carried away. I'm not trying to convince you, just to present as many of your options as I can think of.
I only run DW because it's something to do, not because I particularly feel like I need it, and it sounds to me like if I were in your shoes I'd sooner forego DW than go to the trouble you're talking about.
I wonder whether joemikeb will kick in, but I think that some of the stuff TTP does, surface scans for instance, is more important than running DW, and that your money might be better spent on it rather than on an HD and enclosure.
Go the cheap, easy route! The MP and iMac are always cabled up for Time Machine, so install DW on both, and take turns booting each one into FW Target Disk Mode to run DW on it.
