Abominant leading aberrants with Biophagus

Thinking about running a Broodsurge/Xenocult list where two groups of 10 aberrants are lead by an Aberrant and Biophagus each, while neophytes sit back and sit on the points.

The two Aberrant squads sound terrifying, my only concern is that those two squads are 435 pts each. It seems like they would be overkill.

I've been running Broodsurge for a while and usually took 3 units of 5 (2 abominants, 1 biophagus), and it's always done well like that. I think I just got excited that the Aberrants could take both leaders in 11th. Wondering if anyone has tried it yet.
