Firstly, buy a Perfect Prep.
Secondly, there's no need for 2 people to do a night feed. My DH and I took shifts overnight so we were both getting a decent stretch of sleep. DH would do the 1/2am feed, I'd get up at 5am. Easy. We'd only get up to help if DS was really screaming the place down and it was obvious that something was wrong. We live in a flat, so all on one level and the kitchen/living room isn't far to go from the bedroom so we'd just take DS as soon as he started fussing (or quickly nip to the loo if we needed to, luckily he would fuss and chew on his hands for ages before going into meltdown mode), go into the kitchen where we had everything ready to quickly make a bottle (oh Perfect Prep, how I love thee), feed him on the sofa (very boring, no eye contact!), then take him back into the bedroom to sleep. Worked a treat, we were both tired, but neither of us was properly sleep deprived, which is as good as you're going to get with a baby.
Since your DH has to be up at 6 anyway, how about he goes to bed early, you do the 11 & 2 feeds (or whatever they are) and he does the early morning one and stay up, letting you sleep? Once you get used to it, it's not that bad. I assume he's home around 3/4pm so he can have an hours nap or so when he gets home if he's that exhausted from it. 
I don't buy the concept that because the man is out earning the money he shouldn't have to do any night feeds or caring for baby when he's at home. Maternity leave is no holiday and you don't get a break. What about when/if you go back to work, who will do the nightly get-ups (not every child sleeps though at 9 months +), will it still be you since that's the routine, or will it be shared? Better to have a fair system in place from day 1.
