The outer wire would be intended to carry either a light weather jib
or a reacher. You would probably make most use of a smaller jib
on the inner wire and it seems like you are furling
a sail on it. Furlers create problems for hank on sails
and force you to hank that sail somewhere else.
Maybe you could rig up a removable inner forestay and hank the storm jib
on to that. It is much safer to connect a storm sail mid deck
than out on a bowsprit
. Is there a staysail fitting in the middle of the foredeck ?
