I'm in about the same boat as you with cheek issues on a Cabela's Hawken. I'll use the same approach I do with GPRs- Cut and shoot. The cheek piece and comb seem "massive" to me on both models, so there's lots to work with.
I start by "thinning" the cheek piece, doing nothing else but taking down the thickness. It works out for me to cut them down to about half thickness. In the shop I close my eyes, shoulder the rifle, then open my eyes to see how the sights align.
Once I have the sights lining where I want them, I shoot it for a little while to get acquainted with the new feel. If I'm happy, then I move on. I usually do the comb next, because I find I still have issues with cheek bone pounding and head height even though the side-to-side adjustment is right. Gotta go gentle with how you lower and shape the comb though, because it's sure easy to throw off the lines and proportions. More close-eye shouldering followed by shooting, of course.
Once I have those two dimensions right for my face and build, I go about shaping the cheek plate and fine tuning.
