1500 GK balanced

So with Christmas come and gone I got enough stuff to make the following list:

Librarian, warding stave, 3 powers (sanctuary, shrouding, warp rift)

6 Purifiers, 2 psycannons, hammer, 3 halberds, razorback with psybolt ammo

10 GKSS, 2 psycannons, hammer, psybolt ammo, rhino
10 GKSS, 2 psycannons, hammer, psybolt ammo, rhino
5 GKT, psycannon

Dreadnought, 2x TL Autocannons, psybolt ammo
Dreadnought, 2x TL Autocannons, psybolt ammo

This is the trimmed version of the 1750 list I posted in the other forum. My only concern is how to deploy the termies+libby; I was planning to foot slog them!
Is this a good idea?

Will I be able to hold my own at 1500pts with this list?

Yeah you should be fine. Its all about how you wanna play anyway. Clearly you like power armor playstyle, so go for it and see what happens!
