Doing anything like this would require the necessary support mods (intake, header, exhaust), engine management, and tuning. If you've got emissions testing in your area, you'll also need to factor that in to the equation.

Any stage "2" cam is going to need a higher compression ratio to even be worth it. If you've got stock compression, don't bother. An all motor build takes a decent amount of time, planning, and money to do it right. Finding parts for the 2.0 Lude may be quite challenging as well.
