I would shorten the barrel. But first I would see how much weight needs to be removed to get the balance you want. Lilja and some others have barrel weight calculators. I also would tape weights to the stock and get an idea that way. Or I may just cut it down to 22-24" have a recessed crown done as this seems to reduce muzzle blast and then add weight under the recoil pad until it felt right. I have added weight without shortening the barrel before and it is surprising that not only the rifle balances better but felt lighter and more lively even though in reality it was a couple of ounces heavier.

A new barrel or turning the existing one down could be close to the cost of fluting. The taper could start in front of the fore end and if done well would not be that noticeable.
