1500pts of nuns 'n guns(list modified)

[Hanska]

Just made a list of pure SOB to be a jack-of-all-trades. Usually I've been fighting CSM so I'll need some comments and stuff.
All suggestions are welcome but bear in mind that there are some style/mini based selections(mainly 'dozer blades and combi weapons. I just love them)
Well here is the list:

Canoness
-eviscerator, plasma pistol, book of st.lucius
Celestian bodyguard[4+1]
-eviscerator, h.flamer, flamer
Rhino
-x-tra armor, smoke, 'dozer

Battle sisters[9+1]
-2x meltagun, power weapon, combi-melta, book of st.lucius
Rhino
-x-tra armor, smoke, 'dozer

Battle sisters[19+1]
-h.flamer, flamer, combi-flamer, book of st.lucius

Battle sisters[19+1]
-h.flamer, flamer, combi-flamer, book of st.lucius

Retributors [8+1]
-4x h.bolter, book of st.lucius

Exorcist
-x-tra armor

Exorcist
-x-tra armor

EDIT: Added 500p more for a 2000p list:
Canoness
-blessed weapon, inferno pistol, cloak of st.aspira, rosarius, book of st.lucius, jump pack, frag. grenades

Seraphims[9+1](canoness joins here)
-2x twin inferno pistols, eviscerator

+4 Celestian bodyguards

Models in army: 69(84)
Faith points: 7(10)
Points: 1500(1998)

EDIT: List modified. How about those 2 points?

[Melissia]

Honestly , you'd be better off combining the seraphim into one squad. You don't want to rely upon faith points every single turn to protect two squads-- remember that you have to declare that you're using Spirit of the Martyr at the start of the phase, so you don't get to choose based onw ho the enemy is targeting.

[Hanska]

Hmm.. That is a problem that the squads are so small and can be wiped out with some luck and a few rapid plasma guns. They were a compromise(always bad) for what to use the remaining points for. I thought what to take instead as combining them(bulking the "retinue") would leave me some 50p. Where should I put those?
I thought that I can bulk the melta seraphims up to 7+1 and take a celestian squad with veteran, book and a multi-melta. This would keep my 2000p faith at 11 and a small squad that either is not a tempting target or takes fire away from someone else. I just can't think of anything else to fill the points.
UNLESS I go not pure and take an inquisitor with a bolter and eversor assassin. This gives me a usefull cc monster but also a useless kill point and drops my faith to 10.
ANY suggestions for that?
Making a good list against my usual opponent is easy as 1-2-3 but making a all-round list is definetly new to me.

EDIT: Damn I'm just stupid. Now I got it. I'll bulk the seraphim squad to 9+1 and the original canoness' retinue to 8+1. This leaves me with 2p. An auspex for the retributors or search lights to exorcists?
