Interesting engineering. If simply as an idea (rather than a purchase) then I would go Dougals route - but is still captive either way ie t/c off if breaks. If purchased then lots of work yet to be done so my guess approaching a thousand dollars if not more. This is how I understand it.

Rakeway have this (half way down). Looked at this when could not get hold of Sheldon to get a kit. The closest to our idea of field serviceable - but their overall design is not field serviceable. The SAE10 slides into the drive flange via a spline set - the SAE10 is then bolted securely into the flange. Again captive, t/c off if it breaks. Got to mate the LRover flange to a second flange so you can mate it to the Isuzu flange. Might work. I would not bolt the SAE10 to the drive flange but use detent or c clip as discussed earlier to hold in place. Then maybe you have something. But from memory when I enquired they could machine a different flange, but as a one off again very very expensive. Even their unit as you see it is not cost effective from memory given what ever adapting you may have to do. Guess you could go remote mount but all the extra work!?
