Hoi: We most likely wouldn't go for that for a few reasons:
1) It very clearly didn't glow in the films. You can imagine that they might paint the ATAT differently to what you saw in the films, but it's harder to imagine why the cockpit is suddenly glowing red.
2) It isn't a robot, it's a giant transport.
The slit isn't for eyes, it's where the pilot sits.
3) While red might make it look angry, if it is teamcolour, it could just as easily be pink.
And perhaps more importantly, for gameplay reasons:
4) I should've noted this already, so I'll say it here:
teamcolour needs to be visible from as many angles as possible, and at the very least from the overhead perspective at all times. If it was only the eyes glowing, then you may not be able to see it from overhead, particularly if it is aiming down at something, and you definitely wouldn't be able to see it from, say, a Total War camera view when it is facing away from you.
EDIT: Sorry, on close inspection I see you have put some other glows around the unit - most of what I said above still applies though. I'm not sure if it is possible to emit a CEG with the player's teamcolour, so it would have to be done with glows in the texture. It's certainly a possibility, but the fact that I didn't really notice the other areas other then the cockpit perhaps suggests that this wouldn't be obvious enough...
Jazcash: Not really possible with Spring at the moment.
