That art lines up with the Int 2 pilot with a short name. This green paint scheme was only used once in Clone Wars, to my knowledge, and was used by R2, which means that likely for that one pilot instead of having an astromech slot it will instead have a crew slot, hence 3PO.
For the other pilots
We have Anakin's pilot art. As a fun aside, anyone find it amusing that we have had 3 Anakin's in a row, Wave 3, Delta 7, Wave 4, N1 Starfighter, and Wave 5, Y-Wing. If we stay with that trend maybe well see him as a pilot for either the Eta 2 or Twilight for Wave 6.
and Odd Ball's art
This leaves us with 3 more named pilots. The Int 4 pilot's name seems to start with 'M' so I'm going to guess Matchstick, which leaves us with an unknown Int 3 and Int 2 pilot. The other Int 2 pilot's art seems to be from the Malastare battle where the electro proton bomb was used.
