With the release of the Chimera Heavy Destroyer (an amazing ship by the way) one of its effects from its universal console - dynamic tactical system is an enemy shield steal. If the devs want they could give this to Aegis because it goes in line with the whole shield/damage resistance theme of the set. This is just one idea to play with. If other people object strongly then we could go with something else.
As for the Remen set, I was thinking maybe some sort of mask energy signature or jam sensor. I believe that this goes towards the the Remen/Romulan theme. Devs just pick one and beef up the stats slightly because its attached to the set.
