I would allow it to ferment for a few weeks, then transfer it to a carboy on top of oak. The pelicle won't form in the first few weeks, so you'll be fine there.
I usually ferment my sours with US05 until they're about 80% fermented. Then...depending on what type of sour (some I use a secondary on, some I don't) I'll transfer it to a secondary where I'll add the oak, pedio, and lacto. I add the brett at a few months in. The oak will eventually hit a peak and then start to mellow in time. By the time you drink these beers, you probably won't even notice it's there.
