To answer the question, no its not a bad idea.
With the .2 coils being pre-built Id bet that they measure out over .2
As far as them being too hot, depends on your preference. It will def be a warm vape bc youll have to run atleast 25w or so Id think just to get it running IMO.
Youll burn through juice quicker, and battery life too.
That being said, I have a mvp pro also and I love it. I use a STM on it and build on the RBA anywhere from .3 to .7, I change it up alot.
