THat does look sweet. I'm about to fly a 1/10 scale hornet myself...been saying that for the better part of a year...
One way to keep the hatches and the rest of the fuse plug "matched" while you finish the glassing, would be to add the same layers of glass to the hatch plugs that you do to the main plug. THen the buildup thicknesses would be the same and the edges should sand to match.
