Awesome pictures. Thanks for sharing!
The bow should be no problem. No carving needed, if you can redo the handle wrap you can buildup a shelf under. (I can't tell too well from the pictures, it looks like the bow is thinned out a bit on the arrow side. If that's so than do turn the bow on end but don't worry about carving out a sight window or anything silly like that. Cool bows, like his, don't need one. :p )
