Not so sure about that, Taz. The way the monsters currently work, colonizing will be a problem. Most of the monster concept is based on the premise that they don't colonize.
They don't really need colonies to be dangerous. Their homeworlds are similar to Proportions Mod homeworlds with a 'monsterous' intel output. Resources are not a problem for them, since their hulls have such a large maintanence reduction that they actually produce resources. All their hulls have quantum reactor, so range is not a problem either.
If they would colonize, then there would be ways for a human to get a hold of their colonies and capture those super-facilities. Also I kinda like the way it currently works that you have to destroy their stars to beat them.

It certainly could be done and I believe I might have found a way to get around the intel problem in a different way. That way they would even be able to do some offensive intel without being too overwhelming. I might just do that and also create another monster race that behaves more like a 'swarm' that also seems to be interesting.

So, to make a long answer short: Yeah, could be done with a change of the current concept. But it certainly would not be easier than a few mouse clicks in the game setup, though.
