Do you have a good floor corker? Usually those are needed for getting the belgian corks into the bottles and can be kinda tricky. Additionally belgian beer bottles are very thick throughout, but especially at the neck. Not sure if a std wine bottle would stay intact as you are putting that much pressure on it. I'm not sure whether a belgian beer bottle has the same size opening as a wine bottle.
I would stick with standard #8 wine corks if you have one of the cheaper corkers (I have the one you hammer on the plunger). If you have a better floor corker or lever corker, you could probably use #9 corks which are a little larger. They should help combat air intrusion and limit long term oxidation vs a #8.
