It's possible to train all and can be of use. Though it can be most adviced to train mainly train your main way of shooting.
And changing it up sometimes while shooting a single magazine is possible.

Important:
-Right handed shooting: Right eye open and for aiming, left eye closed
-Left handed sooting  : Left eye open and for aiming, right eye closed
Being able to hold one eye open and one eye closed at both sides is a good skill.
-And you can train this for both eyes
