Help me out! Quick Question!

Hey guys, I just had a quick question. I'm looking to make a Jan Vesely-esque my player, one who is around 6'10 and 225, and whose primary position is SF but secondary position is PF (NOT the other way around), and whenever I try to use different SF playstyles like athletic, slashing, all-around and defensive, the result is always a SF/SG rather than an SF/PF. Have any of you created an SF/PF, and if you have, what height/weight/playstyle did you use? Thanks!
