In general, I think that your idea has merit if you plan passage
making... some means of reducing sail if the roller boom and all its bits and pieces should have a problem.
But, I wonder if the physical structure of the Leisurefurl boom will allow internal reefing lines to be rigged? One can run them externally, but it is kinda tacky and prone to fouling. I suppose that one could simply setup the hardware
without reeving the lines until needed, and hope that they would never be needed!
Anyhow, I think that it is a worthwhile plan, and would be interested in how you solve the issue... someday I might want to do just that!
Cheers and good luck with it.

PS: I'm not familiar with such a big Freya design. Is it a stretched Freya of old Australian renown or something totally different?
