I ended up doing #3, but with no remesh. I went to buy remesh, and it was too heavy for me to install/cut/manage by myself and didn't fit in the car. Since it wasn't called for anways, I dropped it off the list.
It took about 8 hours to redo everything, and virtually $0. I am happy that I did this, especially since other compromises will come up during the build that I am sure I will have to look over.
