No idea. There are so many variables to consider here. Are you able to get enough feeder roots to sustain the foliar portion of the tree? What is the weather like in the coming weeks and months? Is this particular tree healthy enough to survive transplant in the first place?
IMO Spring collection is a much better bet. I realize that some on here think that a summer repot is fine (there's a big recent thread on it), but that's is really dependent on your local climate, upcoming weather, and your skill level and experience. Here in CA we have an annual drought during the summer. That along with temps hotter than hell in August and relative humidity non-existent make repotting a bad idea. You may be in an area with mild temps and are getting rain. That would certainly help with your chances.
Good luck. I also meant to mention that misting the foliage a couple times a day after collecting will help.
