Sure, if that rocks your boat.
I don't see the point, since all a "build" phase for Roku does is create zip bundle of the needed files (there is no pre-compiling) and what a "deploy" does is to http upload that to the player, which as side effect also "run"s the app. I just use half-dozen-line script to build-deploy-run from my text editor, it is fast enough i think of it a simply "run".
