Help with merging chamfer and countersink angles

Hello Everyone,

I am currently struggling with a project that I am working on, and I wanted to see if anyone had any tips for me with the right way to fix this issue I am having. I am currently trying to update a design I have been working on, which is pictured below. In this design, I am trying to create a channel in order to allow a screw to sit above it while locking this top piece into place relative to a lower piece. I am also attaching a photo of the full design to help with understanding how this piece interconnects with everything else.

For the updated design, I am trying to give it a self-tightening mechanism as I turn the piece without needing to tighten the screw slotted in place by changing the angle between the open hole and the curved section at the other end. My current plan is to have the angle on the right be the same, but on the left side of the opening, having this be flat with the top, with a curve connecting these openings. I have tried using a bridging curve to get the specific shape I am looking for, but I am unable to extrude it in a way to get the correct shape like what I have in the original design. Does anyone know of any other tools I could use to create this curve successfully.

Here is a link to the document I am working on:
