Is there ANY way to peak biceps if you don't have a natural peak?

this might not help but...

i flex my right arm ALOT, not at the gym, but throughout the day, ever since i was a lil kid.. its a habit. anyway, my right arm is much more full and rounder then my left, with a better peak.

i do believe if u flex a muscle enough, it will change. of course u cant make it the way u want, but it might help.

try posing 3 times a week for a few months. it might work

Adding to the above, most people have a noticeably better peak in their dominant arm - look at Arnold!

This means that you MUST be able to do something about it.

I would say that exercises that give a peak contraction - force at that the fully flexed position encourage peaking.
