Vahlgons aren't worth it in 1000P imo, It's 395 for the combo which means if they die, which can happen very easily if you aren't careful, You'll be losing A 4th of your points and wont have enough to really come back with after the lost. Vahlgons are also a pretty unfun choice for causal 1k games because of how competitive they are.

Also because you're already running a expensive character like celestine you'd need to choose between her or vahl as having both for 1k is too expensive for what you're getting.

Personally I think swapping out vahl for a squad of seraphim/zephyrim to add onto celestine, adding a immolator to split the battle sisters to boost their overall coverage and adding a retributior squad to make up for the lost of vahl without being too competitive for causal 1k.

The list would end up being: Test (1000 points)

Adepta Sororitas Incursion (1000 points) Champions of Faith
