actually the first place to start is with prop rotation and prop type. Maybe higher rake? what have you tried so far? not sure what you would do to a hull . . . add rocker?

Weight in the bow of the boat is a big game changer.
Weight in the stern seems to have a pretty big effect as well.
Propwise:
Less blades= (less stern lift) which translates to more bow lift
smaller diameter= (less stern lift) which translates to more bow lift
round ear blades= more bow lift
Hullwise:
Making sure there is no hook has got to help bow lift.
(It feels impossible to lift the bow when you have a hook)
A little bit of rocker in the hull seems like it would assist trim induced bow lift
Not sure about the chines- maybe larger/wider strakes would help but not sure on that one.
