Conventional or Unconventional in developing team identity

Our starting unit is a mix of both.
Harden is a 2guard that plays like a pg and facilitates our offense a lot.
Beverley is our "3 and D" guy that sets the tone defensively while making the occasional three ball and can affect the game without the ball next to a ball dominant guard.

Our more traditional guys are Howard who is an old school center that lives in the paint offensively and anchors the defense.
Parsons is also more of the prototypical forward that can do a little bit of everything and provides versatility to the team.

Which brings us to my question... What kind of PF would this group need?
A traditional POWER forward who is the enforcer type and shores defense/rebounding/toughness and can hit the 15 footer here and there?
Or do we need the new wave of stretch 4 that can space the floor and make our offense unstoppable.

Based on our roster so far, we really can go either way and that pf will pretty much dictate our identity and style of play going forward.

I imagine Morey already has a plan to address this issue in free agency or trade.
Also, are our current youngsters Jones and Dmo malleable to fit either role?
Thoughts?

 

There are very, very, very few of those around.
Milsap is the only power forward that i can think of who is above average at all three of those categories you've mentioned.
