Yeah, giving some roughness to the surface is a good idea, but the carbon would be weakened, as it would also be by drilling it.
I don't think either are really necessary, but a light scouring with say 240 grit emery cloth would help, to remove the old glue from the surface of the carbon, and if you can get inside the lugs to remove any glue and probably some oxidisation from the aluminium.
Drilling it and putting screws in wouldn't really help, and would certainly spoil it!
Also looking at the picture are the chainstays bonded to the shell too? Might want to make sure they are secure!
