Thanks for all of the good ideas all.
My buddy convinced me to come over, transfer 1 gallon for bottling and the rest to the keg. I should get about 10 bottles to condition and consume independently. I calculated needing 24 g of table sugar for priming which should yield more consistency than I was planning. The keg will end up with less than 5 gallons but there will be 3 other beers on tap that night so it shouldn't be a big deal.
