Hmm, reminds me alot of my age old Tau Avenger Battlesuit...
"Even before painting the first Tau warrior I started to build the Avenger Titan-suit. As mentioned above I do like Gundam. So why not use one of my Gundam models, convert it a bit, paint it in the colours of my Tau army and design some rules using the VDR of GW? The best thing about the Bandai models is that they are fully posable. Nearly every joint can be moved. You can also change the weapons and hands. You can literally play with these models.
The whole thing started as a Gundam 1/144 Custom arms model from Bandai. I only modified the head to make it look a bit more like the Tau. The hands are of course still wrong because the Tau with their 8 fingers and 8 numerical system would not build an Exo Suit with 10 fingers. The lower leg / foot part is also not really tau-ish in appearance. "
