Loopback interfaces on L3 Switches

Disclaimer I should know this but never really use loopback interfaces so bear with me. If i have 2 switches connected via a trunk port and i want to create a loopback interface on each switch in the same subnet. Will it use the native untagged vlan to pass that traffic from switch to switch? What if the native vlan is vlan 1 and is already used :(

Thanks in advance.
