Eh, don't worry about yield... worry about survival to harvest!
I'm running the same size space for my flower room with a HPS1000. May add a second, or also run my 400 in there. But 1k is plenty to work with.
If you're vegging in that same space, you can go a little smaller on your MH. Just keep your plants clustered close together and the light low. a 400 is fine.
As an aside, if your mate's grow went all to hell (security or crop failure?) make sure you know why, and if it was security, be careful, because you don't want the same fate.
Good luck
