47-55.1 Anyone extend 1950 Suburban or panel rear fenders

[Thrill4130]

Just starting to start on my 1951 Chevy Carryall and I'm thinking of stretching out my rear fenders. Ive been looking for pictures of anyone that has stretched these out length wise not width. My idea is to add 4 inches in the middle then also raise it 2 to 3 inches. This is a rust bucket so it would help me not have to rebuild that body line that's all rusted out. Also I always kind of felt the little rear fenders looked a little small. I plan to use some 30.5" diameter 215/85r16 dirt knobby tire front and rear so I am hoping this makes fenders look proportional. Im also hoping this makes the rear of Suburban not look like its so tall in the rear since the back gets taller in the rear if you look at the drip rail.
Thanks for any help. Plus Id love to see any other dirt tire or 4x4 suburban builds.
