Sour Wheat from Bottled Beer

[EvolutionAles]

Trying to make a fermented and carbed wheat sour. So I've already brewed a plain wheat ale and naturally carbed it in the bottle. There are two cases of this beer leftover and it's just boring so why not experiment? Is it possible to take the bottled beer and pour it in a secondary fermenter, add some fresh fruit & lacto maybe some pedi? Am I attempting the impossible? Has anyone does this before without causing oxidation?
