In my opinion I wouldn't bottle regular beer in lambic bottles because it is too big a task. The bottles are designed to hold lots of pressure, so they require corks and wire hoods or use special Euro bottle caps. It's easier and cheaper to use regular beer bottles.
I just have to let you know that lambic is almost never bottled, they drink it on draft in Belgium and very rarely export it. We buy is called gueuze, which is a blend of several lambics at different stages of maturity. The biggest difference is that gueuze is highly carbonated (hence the sturdy bottles) and lambic is "flat".
