#1 thing you can do is change oneiros training to guardian training, unless you really want to stay all gallente.
Oneiros is only really used as solo logi due to it not needing cap transfer, so people fit it for kiting with a local tank. However for multiboxing you wont be doing any kiting which means that you will often get neut pressure on logi and you are going to take more damage then when you are kiting. The guardian can fit 2 cap transfers which allows it to either be super cap stable in almost any situation outside heavy pvp neuting, and it can fit a better armor tank then the oneiros.

In short, change exequror to augoror and oneiros to guardian. This will make things ALOT easier in the long run and unless you are already half way through gallente cruiser V then it wont be a big drawback. You wont regret it once you try it :-)

Apart from that you seem to have a good grasp of things. After getting your toons to dominix i would focus alot on maximizing your dps. Get t2 mediums/sentries, drone interfacing IV and gallente battleship IV.
