Good afternoon. Yes, you took a risk making this model. This is a bold step, good luck and patience to finish the model.
Unfortunately, you will not be able to fix it, you have gone too far, the feed is absolutely not correct. To fix something, you need to break everything or start over and go the other way. Use prototype drawings.
I do not know how to help in this situation, you decide. I would put this model aside and do something simpler, but correctly and efficiently. You need to strongly raise the theory for a complex model.
Good luck
