There are a lot of - if not exactly 'wasted', then inefeciantly spent points in your list - I beleive we can scrape up enough for that Rhino.
Personally, I don't like Celestine - lovelly model and not a terrible unit, but she just doesn't do it for me - if you like her than you take her and best of British luck.
Concerning Troops:
The Brazier of Holy Fire / Combi-Flamer debate. For me, there is no debate. The Brazier nets you one additional attack in Assault - but Sisters are plain bad in Assault and nothing will alter that - the Combi-Flamer is so much more effective and Divine Guided Bolters are our bread and butter.
Play to your strengths and choose the Combi-Flamer.
An Imaginifer is rarely worth it in a Battle sister squad. Ten women will pull of Divine Guidance very reliably and only have to loose three before Spirit of the Martyr becomes easy. Those points could be much better spent.
I think you'd find things much easier with a Meltagun in your Battle Sister squads, instead of that regular Flamer. It's something of a matter of taste, but I'd rather have it and not need it than need it and not have it. Same goes for Meltabombs for the VSS.
I also like to hand out Eviscerators to 1/2 to 3/4 of my Sisters Superior - so useful, so cool.
You might loose the Power Weapon from your Dominion squad - it has only limited usefulness there (An Eviscerator on the other hand...). Same goes for the Imaginifer.
Dominions with Flamers benefit from an Imaginifer, as do Retributors with Heavy Bolters - but it's dificult to see what Act of Faith 6 Sisters with AP1 weapons need help with.
Lose the Holy Promethium. Hardly ever worth it, no matter how cool the concept is.
Nothing wrong with your Seraphim, though Meltabombs can be a bag of fun for them!
Exorcist is okay too - you'll want another, but I understand it's not as easy as that.
This is all sounding very negetive, but that's the nature of an army list thread. I can only list flaws (and I have been wrong before).
The assumption is that you are looking for something optimised - if you have a theme, like I do then you do it and don't let anyone tell you not to.
Long story short: Loose the Imaginifers, add Meltaguns and a Rhino.
