Why? Would anyone even think of going to a flying field, to have your aircraft scrutinized by other modelers that wasn't sound in construction?
Why? Would a Person that has pride in his work show up for others to see other than good workmanship?
Ken, was asking a question as to how and possibly rectify a mistake in construction. Yes he asked if it would fly! Possibly! But, do any of you know if THIS! Aircraft will fly as the rest of you assume it may.
Are you going to be responsible for his aircraft if the wing separates? How far out is the alignment? Do you have enough aileron control to recover from an aircraft that violently turns away from the Bad wing? Is there spectators that may be hit by debris?
Safety First. Don't fly an aircraft that may be subject to and incident. You have enough things that can go wrong with Radio gear, let alone a construction problem that may cause it.

Fix the problem.
