Yep. They're survivors just like everyone else. As long as they have an srv_xxx.big and an srv_xxx.tex file, you can place any survivor anywhere you want if you understand the coding.

The only characters that don't seem to have an actual survivor file are Tim Duggan, Justin Tetherford and Emanuel Tugman, as far as I can tell.
