Epic Ships are forbidden from taking bonus actions.
However, neither "Dutch" Vander's nor Colonel Jendon's ability are actions.

Therefore, I see no reason why the Cr-90 or Raider cannot get free Target Locks from these ships.
Thoughts?

Sounds Kosher to me

That works just fine.

Acquiring a TL via Dutch triggers weapons engineer. Receiving a blue TL token from Jendon does not.
