Aquagate mod?

I have the chance to get a coolermaster aquagate unit cheap, but i know these things are a bit limited in their heat dissipation because of the small radiator, however i really like the computerised controls and monitoring, and the auto shutdown feature. There is no possibility of fitting a bigger radiator, so I was wondering if you could replace the waterblock with one of those new thremaltake heat exchangers:

the aquagate isn't designed to be modular, but this pic of the aquagate http://i18.ebayimg.com/01/i/05/95/c0/c6_1_b.JPG
suggests that a custom cooler might be fitted.

I belive the pump in the aquagate is built directly into the waterblock, so no. Plus that TT cooler is a waste of money.
