Follow your heart. Opinions are like elbows, almost everybody has them. I agree with some of those requests. First of all, you have a long action. Forget the "short" cases especially the 6.5-.284. You will probably have to alter the feed rails to insure proper feeding. If you want a short case get a short action. Obviously you aren't obsessed with high velocity. I don't have any experience with RemAge barrels, but I've heard a lot of good about them and in fact my next build will be one. I have the luxury of access to a machine shop, so I do all my own work. Trueing action is easy, and most of the time lapping the lugs takes much longer than machining the reciever. Unfortunately, recoil is a necessary evil, so we have have to put up with it. the only way to lessen it either slow the the bullet or install a muzzle brake. "Felt" recoil gas many factors. First of all every action has a equal and opposite reaction. The energy formula is E=Mass times the velocity squared. Mass or bullet weight has to change substantially to make a difference in energy. On the other hand small changes in velocity make a difference in energy because the velocity is squared. To make it simple, a 10 percent increase in bullet weight will result in a 10 percent increase in energy. On the contrary, a 10 percent increase in velocity will result in a 20 percent increase in energy. So compare a 6.5-06 with a 120 grain bullet and a 30-06 with a 150 grain bullet. The 6.5-06 at 3100fps has 2560 foot pounds of energy. The 30-06 at 3000fps has 2997 foot pounds of energy. That is a little less than 15% difference. So, install a good recoil pad, get a heavier stock, install a muzzle brake, or decrease bullet weight or velocity. Face it, you just want something different. The 270W and the 280R basicly have the same recoil as the 30-06. So, get RemAge barrels in 280AI, 6.5-06AI, and 25-06AI. Play with them and see which one you like the best. Then send me the other two.
Good luck.
