it could be easy, buy yourself a cheap sporterlike this https://auctions.morphyauctions.com/_C__ST__ETIENNE_MAS_36_SPORTER_BOLT_ACTION_RIFLE_-LOT494653.aspx

I have the front and rear sight for an 8 mm that can be used for any other caliber up to 8 mm maybe thicker. it would be very simple for a gunsmith to softsolder this parts giving the distinguish look to the rifle.
