One of the things that makes a marksman shoot well is confidence in their rifle. If that confidence is shaken, sometimes it can't be easily regained. If replacing the stock, or rebarreling doesn't seem feasable to you, trade the rifle in. Or sell it to finance the next rifle.
As an auto mechanic and bodyman, I'm used to tinkering with things to revert them back to original form or convert them to improved form. Something like your problem would drive me insane until I fixed the issue. It's the mindset of what makes a talented mechanic. Not everyone is a mechanic, however. If swapping out parts isn't your thing, not to mention waiting on super busy gunsmiths to do the things you can't for yourself, then the LTR is a faster and better solution. It can be exasperating to spend a lot of money on a rifle, only to find it's a lemon.
I know that if I spend money on something, I want to play with it right now. I can wait on a project rifle,because I have several others to mess with while waiting. Not everyone has that opportunity. Get the LTR, and shoot confidently. My opinion.
