To answer your question, it depends on the gearing and efficiency of your current system. Gearing is easy to determine, efficiency much less so. Luckily there's a simple way for you to answer your question experimentally.

Grab a clamp on Ammeter and measure the max current draw on your CIM while you're lifting. Whatever current you're currently drawing, a second robot of equal weight will likely double it. So if you're currently pulling 30 amps, a second robot would make 60 amps or so. So then it's a question of if you can actually give the CIM that much current. The Jaguar will happily pump 40 amps to your CIM for quite a while. 50 amps for much less so. 60 amps for not very long at all.

So, one measurement and a little math should give you an answer.

One problem with that is that you can only have the jaguar on a 40 amp fuse, nothing larger and only one. We actually tripped our 120 amp at competition this last weekend. Four cims at full power and a vacuum drawing 30 amps from two fisher prices. Unfortunately we didn't listen to the mentor who said "you better put the cims on 30's because you could blow the main breaker and that doesn't reset".....ooopps.
