The goal for me was to remake the game-piece. In the game, the crew is used to keep track of the hit-points, so when a crew member is removed, it's helpful that the game piece shows that.
If you don't make concessions for a microfig, you could make the cockpit solid with fewer pieces. With the construction shown here, the minifig studs get in the way of the tubes under the larger tile pieces. The middle section of the cockpit canopy is a fraction of a millimeter higher than surrounding structure, so it's not a perfect fit to make a one-piece rooftop, either. If you removed the concessions for microfig pilots, you could easily clean up the cockpit - make it solid bricks - and make the top two pieces (e.g. two 1x6 tiles), instead of five.
I didn't try to find an orange sticker. I guess a B-Wing roundel sticker could be cut for the right shape.
