Oh, trust me. I thought about it with every single faction. Genestealers can infiltrate any sentient species so they would work with all but the dummy faction in here.

And the Daleks, though they still may be flesh, I do understand that Genestealers still need to break through their Dalekanium casing -unless I've missed something in lore- and even if you did manage that, the Daleks booby-trapped it to the brim, [i]"Even a dead Dalek is dangerous" - The Doctor[/i]. 

Plus, to infiltrate the Dalek race, you'd need a casing in the first place to install your genestealer-kaled mutate; trust me on this, Kaleds DO NOT look pretty.
