Did you ever finalize your project? Because I will do the exact same thing on my Serek Midwestern, just ordered the parts today. Jerry is a joy to work with! Thanks @Jerry Catanescu!
I'm actually in the midst of drawing out the schematic and layout for my tech. The control route is so small on Sereks that its presenting some challenges to fit what I want in there.
Feel free to share any updates, as you'll probably install it before me! I'm sure it'll be awesome. Which pickup did you go with on your Midwestern?
