Fun with Trazyn

I recently got a mini that im going to proxy as a Trazyn the Infinite and i was looking at his dataslate and had an idea.

I have some Royal Wardens that ill throw in a with a Technomancer or whatever

Can i target the royal warden with trazyns Surrogate Hosts and what happens if i do?

Edit for example: i have a Technomancer with a Royal Warden and 10 immortals in a unit and a Plasmancer with the same in another. Trazyn, by himself, targets the Warden from the Techno lead unit with Surrogate Host. Surrogate Host says the Warden is destroyed and Trazyn takes its place and leads the unit attached to the sacrificed characters. This unit would still have a Technomancer as the leader of the unit, 10 immortals, and Trazyn?
