IF it were my gun I would keep it as walnut Remington stocks may not be so available and would be expensive to replace if you should go back to stock configuration.
I don't mean any harm but it seems to me thet you are not letting any grass grow under your feet when you decided to make a home defense shotgun.
I would ,in my humble honest opinion slow down a little and get to know your gun inside and out so as to be prepared for what ever anomaly may come along.
Take your time and ask yourself if what ever decision you make will be one that makes good of the money you spend and really enhances your gun for the better.
I know how it is to get something and am guilty of not taking the time to plan the action and and the consequence the result.

Poor Performance.
From what I've gleaned, you want a Wingmaster based HD shotgun. That's great. I have three guns (not Wingmasters) although I have had a few in my lifetime and really, one of those that I had I deemed a real nice gun. it was an older 60's model and man that was one slick, tight shotgun.
Slow and easy wins the race and shotguns for HD should be thought out carefully.
Tacticool ain't cool if it provides no real enhancement to the shotgun and empties your wallet at the same time.
