It looks like the doors fit nicely in the well. If the shape really bothers you, I suppose you can use some epoxy and microballoons to create the contour of the gear doors. I used basswood on the inside of my doors, I sanded a slight curve to them, so when I glued the glass covers, they maintained the curve fairly well. Looking at photos of the full scale doors, they actually bulge out a bit with the bulge coaxial to the strut.
