Hmm, stepping back and looking at both the crews, the Kaeris crew seems outclassed in both speed and ranged options. Each time I have faced a Rasputina crew, I look to focus on her ice mirrors, and limiting her options at who she can fire at. This should have the added bonus of drawing her in so you can mob her with you own models. Cover will be very important, especially hard cover, which will give a negative flip to damage.
I would also look at taking Sue, he has great synergy with Kaeris, and can really hamper casters.
