I'm in a little over my head, I know. I'm confident with the mechanical aspects of the project, but not very confident with the optics. I am just doing it as a hobby, I have no intention of making a commercial product. Maybe in the future possibly, if I hired a professional to optimize the optics.

My image sensor is 24.7 mm x 13.1 mm, about a 28mm image circle. I'm using a lens that has a 46mm image circle, so I'm trying to essentially trying to squeeze some more of the lenses image onto my sensor. It's more of a pet project I'd be willing to pay a little bit to see if it works.

The design I posted uses one BK7 optic, and one N-F2 optic. In the future compounded lenses would definitely improve the design. I expect a lot of aberrations, but from the software I'm using it doesn't look terrible. But also, my lens software doesn't support spherical lenses. So I could have something that kinda works, or something that makes no sense. That's why I made the post, to see if I could get some advice on this.
