DIY Ike slave?

Looking at Picking up an old Ikelite 100A for fill. Apparently it doesn't have a built in slave which is a drag but bang for the buck the power output for $50 is without question. really don't want to buy an Ike slave for $100+cable and all that bulk for a $50 strobe. Does anyone out there make a simple optical slave that will mate to the strobe? If not has anyone ever made one? Figure a socket cap drilled out with a standard optical slave and a gob of silicone would do the job, maybe not, lol.

I have a bunch of home made triggers that fit to ikelite wet connectors. Unfortunately I didn't make them, I inherited them. So yes it's possible, but sorry I don't know exactly how...
