I like it but if it was mine I would want to get the seat level.
That is the only way it will be comfortable.
What about some 3 inch tapered springs?
I know you want the seat like that to fit the curves of the bike but once you are sitting on the bike no one can see under it because your legs are there and the springs are compressed.
That curve of the bike is broken up by the riders position
