Playing southpaw to use the thumbstick

I finally got around to modding my 2DSXL and am trying a bunch of games I haven't before. But ngl I still prefer to play things such as shooters, which the 3DS is just terrible at due to lack of 2nd thumbstick (and the C-Stick is not much of an upgrade).

In the past I was actually playing with the idea of getting a non-New 3DS just to be able to use circle pad pro.

But now I'm thinking, would it maybe make sense to try to play some games southpaw - i.e. left handed - i.e. use the face buttons for movement and the thumbstick for camera?

Any right handed people playing like that?
