The Braves have 5 OFers: Acuna (R), Ozuna (R), Duvall (R), Ender (L), Markakis (L)
It will make most sense to rotate through those guys in the OF/DH based on pitcher handedness, and rotating Riley in vs LHP.
Ozuna is even worse defensively than Markakis, so vs RHP: Acuna RF, Ender CF, Markakis LF, Ozuna DH
Then vs LHP: Duvall RF, Acuna CF, Ozuna LF, Riley DH
Some flexibility will be required to get guys like Freeman, Acuna, and Albies occasional days at DH, but this should be the blueprint for the most part.
The other issue is going to be limiting Camargo's PAs vs RHP, but I have no idea how that can be accomplished since I haven't been keeping up on who may be available.
I'm sure Twitker will find a way to get Markakis in the OF every single day though.
