I was born and raised on a farm in wisconsin and my mother had an expression that works here- "You can't make a silk purse out of a sow's ear" and when the original install was non code compliant, and it appears that was the case, it's sometimes not cost effective to correct it. I assume the inspector approved it right ha ha.
Sounds like the rules for conduit spacing are violated and the conduits are set in concrete so your stuck. I suspect the conductor bending violates the code also even it it's only a splice box. NEC 314.28.
I would suggest a conversation with the inspector and hopefully he can work with you on a solution that involves minimal cost and not break the rules and possibly only bend them a little to fit the situation.
