Just wondering how bad or good would it be to replace my front rigid fork that is the same length as my old suspension fork fully extended, with a shorter fork that was meant to replace a rigid fork in the first place. It would be a change from 453mm axle-to-crown length to 385mm. Obviously the front end would lower down, but my old fork did that anyway as it rode bottomed out the whole time I was riding. So basically the whole bike frame would tilt downwards from the rear axle. Steer tube would be slightly more vertical. Top tube slightly more horizontal, bottom bracket a bit lower.
I did a quick little CAD sketch using a photo of my bike, and by my estimates the frame would rotate down by about 6 to 6.5 degrees. The bottom bracket center would go from about 12" off the ground to about 10". Don't most road-oriented bikes have about 10" from ground to BB anyway? Of course I would adjust the seat tilt angle to compensate, and I have an adjustable stem.
Here's my bike:

I used the pic of the bike to make a simple stick-figure of the bike, to scale. Then I copied it and rotated the frame down about the rear axle and drew in the shorter fork:
Thoughts? Not saying I would actually spend $150 to do this, but would still probably look for a different bike. But if I happened to come across a fork for cheap... what would be the good/bad/ugly?
