Your power bridge idea is probably the most cost effective if the install allows for it. Easier to service in the event of a sacrificial failure of the surge protection device too.
Funny, you're touching on another install in process, a cabin with a projection system. Projector power thru bridge back to AV system secure rack with Furman rack mount surge protector/power conditioner.
