You could try the highest possible front sight that will fit - will allow you to raise the rear sight.
Best solution, if within your skill set, would be to lower the comb height on the stock to allow you to lower your anchor point (requires refinishing of the entire stock). Many modern manufactured muzzleloaders, say TC for example, particularly their Hawkens, are difficult for some, marginal for me, to get a good good sight picture. CVAs on the other hand, have a rear sight in my opinion that leaves a lot to be desired. With their high comb, designed more for scope users, the sights just don’t cut it, at least for me. Here is a typical CVA factory rear sight photograph on an unfired exampl that I own. Late 80s manufacture, pre bankruptcy pot metal painted sight. No good words or excuses for it. Wonder why they went bankrupt? Plan is to replace the rear sight and lower the comb, some day...... Upside, once you replace the sights, lower the comb, and figure out how to work with the breech design (different topic), the barrels can be quite accurate.
