Oh man I wasn't expecting this much feedback so quick.
thank you all. So much valuable info. I've been trying to respond but not getting a chance, so here goes:

I did not even think they had aux tanks like this. They look perfect for the task however finding/forging them will be a bigger problem I think. You're 100% correct as I need to keep CG as low as possible. It's one of the main reasons I think the GW is suitable since the bulk of the engine weight is so far down as is it's main tank. Will keep my eyes peeled for the ones you've linked. My boy is so excited already. He's been busy spending time with his uncle trying to come up with a good name for the project and can't wait for the bike to arrive. Really looking forward to spending some time with him on this project and seeing what he can pickup. Kids these days are in a different league.

I have a CBX550 tank kicking about (although unobtainium in it's own right) which I am contemplating using. The idea is to only fill up from this new top tank and connect a feedpipe which runs down to the original underseat tank. Nothing else will change so should be good...at least in my head it is
Usually you'd tackle my endurance concerns with what's known as a camel tank
But the beauty of the GW tank fixes all this nicely. It's like this fake tank business was actually there to leave room for an endurance build

Again sound advice and although on paper, I have many things noted down, the proof is in the pudding. Air filter will remain as is, I hope
but the filler will become the feedport from the tailend of the 'top tank'...not sure what else to call it. Will have a new cap CNC'd with some form of a integrated filler tube etc. Again in my head it makes sense but we shall see. Weight is actually a huge concern. But, I'm secretly hoping somehow I manage to shave enough off to get it to around 600 pounds dry weight. If that involves new lightweight forks/shocks and anything else inc wheels, then I guess that's where the bulk of the cost is going to be.

haha you're not wrong there. I've spent the last week bookmarking everything that looks remotely needed. Going to be a huge learning curve but looking forward to it. Thank you immensely for pointing out these shocks. I'm already eyeing up a local seller of these so no doubt I'll get back to you for more info. As eric mentioned above, the u-joint is a concern too but I need to gain an extra few inches on ride height. This will have to be through a combination of shocks, forks and wheels. I'm 6'1" with a 33" inseam and weigh a measly 250 lbs
proportions are important as is the ride height and clearance when offroading.

Glad I could be of service
might want to order a supply of extra popcorn as something tells me this will be a long journey.

oooh yes please, do share pics. I think the GW is going to be a joy to ride both on road and offroad. Don't get me wrong I'm not making the next Motocross Wing, however like you say, it needs to hold it's own and be capable at the task. If it can do that, then me along with everyone else watching, will be very happy.

It's good to kick some life into dreams and even more enjoyable when you do it with something that was in no way designed for the task. I'm super excited in one respect, and bricking it at the same time. Again thank you for sharing that post, although my wing will be going on a more aggressive diet. I've looked around a fair bit and the best example I can find of something that somewhat resembles what I'm aiming for, is this '80 GL1100 conversion
however I'm keeping the original tank intact and the rear will have some kind of a pannier rack to be able to strap on bags and water canteen etc.
Will update again soon as I can.
