No you can't.
My 2.5L I4 Turbo will never loose boost between shifts because its backed by a 3 speed auto. Try that in a manual.
Then find out if you can "shift" better than a CVT transmission. CVTs are constantly in the right power range and are constantly efficient.
I've said before, manuals are good for smaller cars, cars without a great deal of horsepower, or cars that are not aspirated. But once you want to tow something, have boost, something that can handle a lot of horsepower, or need to make insanely quick shifts - an auto is king.
