Is one month enough to be a winning player at 0.25/0.5 Omaha high?

[slimbob]

I play poker for 3.5 years now and almost 3 years poker for a living (mostly holdem nl sng and hu and short handed holdem nl)
I played only a may be 2-3 thousand (=nothing) hands omaha high and omaha hi/lo.

I like to give omaha a try. I try to be a winning player after a month at 0.25/0.5 omaha. Is this expectation realistic if i play 4 hours a day and study also 4 hours a day (, read here, reviewing hands, play with the odds calculator, posting hands etc.).

So what do you think? Am I too optimistic?
