I'm not sure that an asymmetrical 'chute is legal for racing, so if that's your game, check it out first. For day sailing, I would go asymmetrical with a dousing sock. Look on Bacon Associates for other boats with similar I and J dimensions and see if there are some stock asymmetrics that will fit. No pole needed and therefore no pole topping lift, downhaul, tweakers, mast track, or car.
Buy some decent lightweight sheets that are long enough to run forward of the fore stay and sheet close on the other side (maybe 2 1/2 boat lengths each). That way you can gybe the sail by turning it inside out forward of the fore stay.
I'd also install an adjustable tack line run aft to the cockpit. It's nice to be able to raise the tack above the pulpit sometimes
You won't need a spinnaker pole, but if you already have a whisker pole, that's nice to stabilize the asy chute on days when the wind is flukey or you just want to relax.
You'll need a pair of turning blocks (Harken hexaratchets) fastened to the push pit. Just run the sheets forward to the primary winches in stronger winds.
Fun to think about! Sail on, Dude!
