Spruce Mast and Roller Furling

I am buying a Mercator Offshore 30 with spruce spars. It has a roller reefing main that rolls around the boom. I want to modify it for a modern jiffy reefing system. Anyone done this starting with a similar set-up? It seems I would need to get rid of the gear that rolls the boom and attach it to the mast using....what hardware?

Also is it possible to add a furling headsail to a spruce mast? Do most people with furling headsails have two stays to allow for flying other sails?

I plan to do much singlehanded sailing and want all lines (as much as is doable) led to the cockpit.

Ideas? Alternatives?
