You can. Take a 2-piece rim one (easier to work with). You then have a choice: you can replace half the rim, or all of it, with something that can handle extra length, or you can simply use longer bolts or spacers, then drill a few extra holes in a sprocket to match the pattern.

330's used 2-piece rim pneumatic casters (6") for a while now, and has figured out how to get the interface working right. ShaneP would know more about how we did that.
