Do not see why not, it only costs $$$. Suggest contacting boom furling manufacturers to confirm requirements and cost below AND your local sail loft to learn what has to be done to either modify your mainsail or quote you a new mainsail for in-boom furling.

You are correct, albeit cost does not appear to be factor in this thread. It would be interesting to hear from the OP on any budget constraint.
The CDI Mainsail Furling System price point is acceptable. How well does it work?
