The problem with doing what you're suggesting... reefing the sail on the roller furler until the clew is forward of the mast and then using a single sheet and turning block are:
1) The sail will be very baggy and have lousy shape because of being reefed on a roller furler. Most roller furlers are good for about a 30% reduction in sail area...but more than that, they get really baggy.
2) Unless you're planning on only sailing close hauled, the turning block for the sheet will be too far inboard for the sail to have any decent shape. The clew will be pulled in and destroy any resemblance to an airfoil shape on the jib on any point other than close hauled.
This second point is kind of the reason they use a traveler track or a jib boom, so that the clew of the sail can move outboard as the sheet is eased...

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
