need combustion air-any ideas?

I have an 1840 Greek Revival house with 3 apartments, 3 ancient forced air oil burners and 4 fireplaces. I've sealed up the house and blown in insulation and have created a fairly tight house. Needless to say I need a lot of combustion air if only for the furnaces. Would also like to occasionally use one or more of the fireplaces. My thought is to build a fresh air intake "trunk" from one of the basement windows and then tap into it at each burner with a shroud around the blower. The "trunk" then could also supply air for the fireplaces via a register as close to the hearth as possible. Can this work? Any thoughts or ideas are welcome.
