Xvive U4 as director/ scripty/ camera monitor?

Hey guys. Have the option to get one of these systems with 2 receivers for a pretty good price (330Aud) thinking I could use them to send to whoever needs to monitor; boom op, scripty, director.

I can’t see why these wouldn’t work with my F8, but if anyone else can would love to know.

My other reservation about getting them is when I upgrade to a proper monitoring system and these just get left in the junk drawer. However I can’t see that happening in the next few years.
