The versys is 205 fully fuelled.
Of course this is the 'daddy' of this kind of machine....
Grafting everything onto the Versys or ER-6/Ninja frame might be possible, but I think it will end up being just as much or more work than a swap. I also doubt that it will work together as well as the LC4 chassis. This guy tried it:
I would also like to end up considerably lighter than 200kg. Around 160kg (without fuel) should be doable, apparently the Versys engine weighs around 55kg (to be confirmed). So slightly more than an LC4, but I can save a bit with lighter muffler, fiberglass fairing, rally tank etc. Something like Jaybo has done on his LC4, except for the rear tank I have almost all the parts anyway:
I have a feeling that a 160kg Adv with a 62+ HP twin would be a lot of fun....

Stick to a single.
I'd put a F650 motor in it, or an x-challenge motor if you can find one. They meet all your demands.
The Versys engine seems to be quite compact. I am going to the local Kawi dealer (who happens to be a family friend) and will get some measurement this weekend. Hopefully I'll get in a test ride as well.
I agree the BMW 650 would be the easiest choice. I might still end up doing that if I find a good deal, but but it wouldn't be anything you can't do with a farkled X-Challenge. Touratech rally fairing, front tank, and steel subframe, etc. Could have just gotten this bike on Ebay a few weeks ago, sold for €6k or so:
