He'd have to be pretty ridonkulous as a hitter to get any team to be willing to risk a pitcher that way. Basically, willingness to be creative with the lineup isn't the key factor here; money is. His value overwhelmingly comes from how well he pitches, and no team is going to risk losing that because of some stupid, easily avoidable injury letting the guy play LF when the reality is as a hitter in the US he's almost certainly just going to be "a good hitter for a pitcher."
