Raising/retractable bowsprit

I am a UK based propective BCC owner and have spent some time sailing the falmouth working boats from which Lyle Hess seems to have drawn inspiration for the BCC and other similar designs. Most of the originals have bowsprits which eithe pivot from the bitts or have a removable pin which allows the bowsprit to be retracted through the gammon iron. I would like to know if anyone has modified a bcc in this way and any problems which have resulted. I would guess that the forestay (stays’l stay?) would have to be beefed up a bit to compensate for having a movable jibstay. A block & tackle bobstay should be able to provide sufficient tension in the jibstay - any thoughts.

Many thanks
