I'm using a 6 gallon carboy, I don't think it would be safe to use a smaller carboy (for primary fermentation) because your beer batch is 5 gallons right? Do you really want it all the way up to the top?
I see no reason why you can't use a blow off tube but you'll have your beer right up to the top. Thats kinda tight fitting.
