Shower Drain and P-Trap

I know there'a lots of opinion on this subject, but I'm moving my basement shower drain (2" pvc--see picture). The stub coming from the floor is the existing p-trap. I've dug an L-shaped trench and am thinking I will just offset the drain and cut into the existing trap without moving it. Is this legal? Advisable? Not a problem? Guess I just need some advide. Thanks.

In many cases it is not legal because the code may say that the trap seal should be visible from the surface. But even it is permitted in your area, it is not a good idea because it could create an odor problem, and make snaking the drain difficult or impossible.
