I've seen that pop up from time to time. I think it actually might play better than one would expect as the prospect of taking down two battleships (squadron?) would not be pretty and might just let either them or the light cruisers get through.
There's also a couple of alternate fleets I have in vs games against my normal fleets:
Retribution
2x Mars
2x Dauntless Lance
2x Endeavour
3x Sword
