How do I get my Character to spawn as a morph, or custom character without 'StarterCharacter'?

So, I turn off AutoLoads, so the character doesn't spawn automatically, and will only spawn with the ":LoadCharacter() " function. How do I get my character to spawn as different morphs, or rather a completely different NPC without using StarterCharacter because I want the StarterCharacter to be changeable, or specific to a team.

Let's say I am trying to achieve something to where if you are in one team, you spawn as an Alien morph/custom character, and another, you'll spawn as a Predator morph/custom character.

Should I just have the character spawn, then instantly morph (or rig) into something else? Should I have the character spawn, then switch the Character to a random NPC, and adjust the camera to it's humanoid? Should I just have a script change the StarterCharacter change locally, is it even possible?

Is there a function that allows you to spawn as a model in the said "void"

Let me know if you have any suggestions, or ideas?
