He certainly is a very good hitter but you don't know how he would hit as a position player.
Problem is that a position player gets not as good pitches to hit. As a pitcher you don't want to waste 4 or 5 pitches to strike the opponent pitcher out. You want to lay him one in so that he grounds or pops himself out with the first pitch. you do that because pitchers usually can't hit anyway and you can't afford 15+ pitches on the pitcher alone (which is 1/7th of a game for a pitcher in these days when a pitcher only goes to 100 or 110 max).
As a position player he will face much tougher pitches more regularly, be taken more serious and also has a higher pressure to perform at the plate. also the sample size is not high.
Owings would be a very good hitter. but would he be better than the average AAA position player? that is the big question because despite sucking right now he still has a spot in the majors. hitting wouldn't guarantee that to him at all so the transition (which would take some time like with ankiel) would be a high risk.
I think walks are overrated unless you can run. If you get a walk and put the pitcher in a stretch, that helps, but the guy who walks and can’t run, most of the time he’s clogging up the bases for somebody who can run. – Dusty Baker.
