Can I bottle after priming in a keg?

I know, I know...call me crazy. I've got 5 gallons of pumpkin ale that has been priming in Tap-A-Draft bottles for about 3 days. (Spent 4 days in the primary, went from 1.073 to 1.020, then conditioned in a glass carboy for a week before priming and racking to the TAD bottles.)

I've got a LOT of friends requesting individual bottles, though. If I open the TAD bottles, which are firm with pressure, can I then bottle the beer individually? Do I need to add more priming sugar? Or do I need to start over with a new batch?

Thanks for all your input, you guys are amazing!

I'm not all familiar with Tap-a-draft, but I assume you could use this: https://www.homebrewtalk.com/f35/we-no-need-no-stinking-beer-gun-24678/

You can bottle in plastic PET bottles, soda bottles, beer bottles, etc.
