Cut Down salvage RV door & screen??

It looks to me like it would be pretty easy to take a standard RV door, screen, & frame assembly and cut it down to a shorter height. Has anyone done this?
I originally considered this plan for my standing height mega tear to replace the Chalet. In that case I would have cut less than 1' off the bottom so the latch wouldn't need to move. Now I'm looking at more of a standard sized trailer with 4' sidewalls so the door would be cut way down. The latch would be remounted.
Thanks
