This comes up a couple times a year... I've posted pics a couple times somewhere on here.
The saying I like for corbin is "as wide and hard as a church pue."
I modified mine. It went from a 250 mile saddle, to an 800 mile saddle.
For the passenger, I chopped off the top 1.5" and replaced it with 2" of appostery foam.
For the front, I hollowed out the thickness of the gel pad and used spray contact adhesive to place the gel pad.
Butt height did not change for me.
Also, just as importantly, I cut the foam to mimick the OE saddle. I cut the carmel hump off that was squishing my nads and chopped a lot off the sides at the forward part of the saddle. Making the seat narrower where your legs reach for the ground makes the seat feel lower when both feet are on the ground.
Then I used appostery batting (1/8" thick cotteny stuff) to hide the small imperfections and seam lines.
This stuff works great and makes the install look clean and not a hack job.
The "foamectomy" instructions help a lot. I did a version of this also, bringing the rider rear support forward.
Removing the skin and cleaning up the mess was 90% of the work.
Warning: this is a lot of labor, like 30+hrs. Remove the skin, foamectomy, go to softer thicker foam for the passenger, add gel up front, and reshape the whole thing.
Also, foam, batting, rivet gun, electric knife, gel; the costs add up quickly. My total cost was over $100.
