Not bad, I would drop some of the dozer blades and give the terminators some Daemon hammer.

Coteaz is nice, just not my cup of tea. Personally I like the idea of having the Librarian and GM hanging with Terminators and this way with 2 Hammerhands and a Might of Titan your terminators are rolling around at Str 7 (8 if you don't need your force weapons)
