Well if all you want to do is control the drivetrain it is very simple. Al you need is the following one of the polarity switches lego makes. I dont kow if they can handle the Amps but you could find out. And a micro motor for each one. the polarity switches work like mechnical speed controllers, so you can buy thoes and hook the micromotors into them. the ploarity switches can be found here http://guide.lugnet.com/set/5120
for the interface its really easy all you have to do is use the IR that the RCXs have ive done it a few times when we have made big confusing robots for demos where 1 RCX isnt enough. Also when we made remote controlled robots for games we made up.
Also you might be able to make the out puts into PWM signals by just pulsing it. But im not the master that Domain. But the RCX puts off 9 volts on a full batteries, so you migght be able to get some help from that info. that all for now if i think of somthing you will hear about it.
