Would I cause a serious problem..No..I can't see where you would. You are primarily using the pistol for shooting and modifying it to your needs. You say It is not a collectible so changing the rear sight would be like breaking a part. Not that serious..just get another. I have a beautiful all matching G date and someone did just what you are suggesting. That change was a tragedy but in your case..go for it I say.
