That wouldn't necessarily be working too closely with the Inquisition, if he were just a contact/agent they had.
But if his goal is to crush the Chantry or Orlesian nobility, the Inquisition wouldn't really make sense as an organization to give his allegiance. The Inquisition is Chantry-aligned and allied with Orlais, it's led by Chantry operatives (Cassandra, Leliana, Cullen), and it's become even more pro-establishment over the last eight years in Fade Rift than it is in the Dragon Age canon. If he had his own private agenda while working for them that could be fine, but if Leliana or Josephine (or Cassandra or Cullen) got any whiff of him working directly against the Chantry or wanting to deliberately destabilize Orlais, it wouldn't have gone well.
