It works fine. Think of them as growlers. If you have a growler filler, it will work even better. If not, jam some racking tube up into the tap and use that as a growler tube.
I've done this (with probably the same 16-oz swing tops you're describing) and it worked fine. It's obviously not as great as beer right out of the tap, but it's still good.
Tip: Before you fill the bottles, turn your regulator waaaay down to like 5 PSI or less. Then pour yourself a pint before you fill the bottles. It helps reduce foaming while you fill the bottles.
