Ok, don't stone me for reviving what appears to be a dead horse, but I figure that if I still don't get it, then there might still be some hope left.

I've been re-reading all the fork swap threads I can find, dubiously studying the AllBallsRacing fork conversion options, comparing steering bearings, wheel bearings, brake disc diameters, and fork widths, and the best alternative I can find for a raised front end to match a longer rear shock are the late 80s to '92 YZ80 forks that will bolt in to our existing triple tree.
Pretty much every other option requires swapping to a skinny front, which may certainly have some advantages that I don't yet fully appreciate, but I'm not keen on the idea of ditching the iconic TW image by adding a skinny front end.
I particularly liked the pics posted some time ago by JohnnyBlaze. The stance looked good, not quite "balanced" per se, but certainly better that just adding a tall rear shock. I appreciate the dilemma that was communicated on the 12mm vs. 15mm axle bolt...kinda hard to argue with physics, and when you do, you don't win.
On some other thread someone asked the $25,000 question, and in my opinion, it didn't get the attention that it deserved. So I'm going to stop typing shortly and get to the point:
TW200 & early YZ80 forks are the same diameter, share fork seals, and have the exact same part number for the little bolt that connects the internals to the lower fork tube. So why can't a hybrid fork be constructed from the TW outer tube and the YZ inner tube to get a taller front fork and balance a raised rear end?
I've noticed that the YZ has what is purported to be a 10" travel, which I find just delicious to think of, but I've also noted that the YZ outer tube extends about 3" below the axle to make up for this additional travel. But travel and whatever spacers inside the fork tube aside...
Why couldn't this hybrid work?

Alright, I'm sufficiently prepared now...and a "newbie"...stone away...
