auto to manual?

is it possible to turn my auto into a manual? i thought it would be nice to have auto for my daily driver, but my 91 hatch is stick, and yea, its nice not havin to clutch in the city, but more often than not i find myself wishing that i would have just gone the other route. if it is possible, does it make sense to do, or would i just be better off to sell her and get another eg in manual? thanks everybody.
