though I suggest that you take my suggestions with a grain of salt, since I don't even have Permission:
I don't think that there's a problem with creating an agent with a backstory in established canon. If memory serves correctly, one agent already does something similar (Agent Suicide), and doing so should avoid the pitfall of forcing a fanon identity--much less a PPC identity--onto an established (albeit a bit) canon character.
