Sorry for derailing the original topic.
The difference is mostly
A ) In the valving
B ) In suspension length
C ) in front offset
For A: You can probably just get the FE valving spec and install it. A revalve is an easy job, done with hand tools.
For B: You *can* keep the length, but you can also extend the travel if you wish.
Bushmechanic has posted about cartridge extenders which extend fork travel. AFAIK these are simple lengths of pipe the same dimensions as the fork cartridge (the innermost tube in the forks). They have a screw thread on the outside on one end and on the inside of the other end. You screw these on, make sure everything else fits together, and you have extended your forks
These can probably be bought, and also your friendly neighborhood machinist can make you some I'm sure! Machining is a super nice world to get into.
For the shock: On the DRZ (the other bike I know a tiny little bit about) there are ways to extend the travel of the shock. These involve changing the length of a spacer as far as I know. Maybe changing the shock shaft; I'm not sure. These are not as major changes as they may seem
For C: I THINK that a supermoto fork yoke may cause FE forks and wheels to steer somewhat heavy when swapped on, all else being equal. The SM yoke has less offset = more front wheel trail = more "steering correction" by the ground as you travel over it because the ground has greater leverage over the wheel and wants to straighten it out. You can alleviate this to a significant degree by making the front sit lower or the rear sit higher. Many ways to do it, including rear preload, fork position in clamps, spring weight front or rear, and even the valving ("dynamic ride height" as Bushie illustrated it somewhere here, worth a dig for and a read).
