The wood will be a challenge. at least with the bolt handle you can start over/ One trick I plan on trying is building in a carbon fiber box beam to hold things straight. Just how I'm not sure, several optinns. Right now carbon bow laminations and spray urethane foam for the core are in the lead. Should be able to keep it all one piece with no warping worries.
Could be the execution of pictures of pieces I've seen but few inlays to disturb the beauty of the wood and almost no carving. The carving there is has that it grew there look. "The gun's plainness is an elegance all its own due to its well thought out lines." That's where my eye takes me along with good wood. I cannot do that and perhaps never will get the flow between wood and steel just right.
