What an exciting stage to be at! Congratulations!
I suspect you'll be fine. You'll probably want the flaps off so you have clear access to the rear spar attachment bolt.
Though I doubt it'd be an issue...If the torque tubes occlude fitment or access at the wing/fuse joint, just push the inboard one out of the way. Again, I doubt this would be an issue, but it if is, you may find it easer to fix the aileron in the full up position so its torque tube is full outboard (be careful you don't push it too far up since there is no stop in the up direction as the counter-aileron's down stop serves that purpose in flight).
Also, I've posted this before, be careful when you tap the bolts in that the web of the F-01404 Aft Center Section Bulkhead doesn't get caught on a bolt thread. Go slowly and keep checking for it.
BTW, if you made a wing stand, it's a great "helper" when attaching wings
