Actually, you wont be able to use the MX jib as it extends to far down and it would conflict the spinnaker pole. I have heard some people cutting a pie shape/sliver off the bottom of the jib to make it work, or just using the MX main and standard jib.

If I were to do it, I would basically thieve an F18 setup. Sheet it to the shroud like theirs. I got a lot of stuff from performancecat, just because of accessibility. I used a the bale for the N-20 on the top and just bent/made it work for the P19 mast. I have seen other setups that do away with the bale, but they all work the same.

All, in all, I think you are on the right track. With the F18 flat cut spin, and MX main and standard jib, the boat will run. Randy Smyth beat a many a boat rated faster, but that is Randy. Good luck and keep us posted.
