No, do not try to cork a 22 oz bottle. Belgian bottles are similar to champagne bottles. They are made to withstand not only the pressure of the high carbonation, but also the cork and the cage. 22's might handle the pressure, but not the cork. Standard wine botles can handle the cork but not the pressure. Find either champagne bottles or belgian beer bottles.
As far as aging, natural cork is going to allow some oxygen to get in that will oxidize slowly over time. Synthetic cork won't, or at least not as much, I'm not a cork expert.
