i made a robot mastermind on Thunderspy; and with a little searching through the costume bits you can find items that more or less connect the robot weapons to whatever figure/model you choose; arm/glove pieces and shoulder pieces. but it's not at all perfect. My fav CoH servers are on Homecoming, as well as a lot my friends. And we all would be ecstatic to be able to customize our pets, on masterminds, controllers, etc., here on Homecoming.
