I think that almost everybody here is assuming that, and Jenna provided a good explanation.
It seems you would like to get help for a VERY special configuration. In order to avoid wasting time, it would be easier if you provide a complete diagram of what you want to do.
I saw special situations with timing hut at the start, but the connections were by wire.
Remember that anything out of the FIS rules eventualy leads to a non homologated event.
If I were in your situation, I would ask to FIS's Cattaneo a written statement.
It's even likely that you may not get one, since you can't simply put together your HW in a FIS-accepted diagram.
