I do like seeing Juno and Echo on the table, and I think the Decoy+Intel Agent combo has merit. However, Tetran Cowall is a painfully terrible pilot who will just act as dead weight on your list, even as a
PS source for Decoy.
Since you're tinkering with less-used pilots, and you have
PS manipulation mechanics, I would try using Epsilon Ace. A PS12 phantom can joust
VI Vader, and it forces your opponent to split fire between the Phantom and Epsilon Ace if they want to shut down that combo. As a fourth ship, I would add in Chaser, who can act as a blocker for the rest of your ships, and will generate free focus tokens when your aces spend them.
I would also give Echo
FCS, and ditch the
EU on Juno.
