For a head, this Backstop is basic enough, with general similarities to Dodger.

Plus, he doesn't have all the popularity and mythos around his character.  In addition, he's from the same year, so it 
might help with neck ball/torso fitting.  I'm not sure, since I don't have Dodger, I can't really confirm this.  
I hope that helps!  Let us see a pic when you finish!
