Whether or not it's advisable is totally up to you - it's a subjective question and each person is different, so we can't answer that aspect.
It'll be difficult, so accept that now and enjoy the ride ;)
I've flown into Novosibirsk, and there were taxis from the airport. So as long as you have the name of your accommodation (or address), preferably written in Cyrillic, you can get by quite easily.
Walk up to a taxi, he'll obviously want to know where you're going. Show him the paper with the location on it, and ask "skolka?" (how much)? He'll reply in Russian, you won't know what it is, look lost, and he'll likely write it down, or type it on his phone. Make sure you get the price before getting in the cab - even if only an estimate.
When you get there, pay, and voila, you've made it to your accommodation (Assuming you have some).
Alternative option: try and befriend a local, if you can, and get a ride with them.
Final option: Sleep at the airport, and get a taxi during the day. The airport has showers, and as per the link, it's definitely possible to sleep there, just be careful about your stuff.
For more information on taxi prices and the bus option, have a look at the Get In section on Wikitravel for Novosibirsk.
