Yup the EA was given light molecular weapons by the Shadows to put on their Omega-Xs (Shadow Omega), they appeared in the series as a blueish beam. In the episodes they appeared, they didn't fire pulses but I suppose they might have updated their pulse technology as well.

How hard would it be to incorporate the Omega-X weapons to the mod at this point?

On the Yolu I have no idea. They were never closely featured in the series if at all and unfortunately AoG closed down before I was able to get any League supplements.
