I picked up the frame, no bells and whistles. The fixed cup is still on there, which will be a ***** to take off but I'll manage.
The goal in mind is budget beater

but i don't mind missing that target, i've got a few bones to drop. The build is half the fun (mech engineer here).
It seems like you'd save weight, cost, and complexity by just getting a fixed/fixed flip-flop hub and 2 cogs. What kind of riding are you planning on doing that requires [roughly*] 70 gear inches and [roughly*] 55 gear inches?
*estimates based on 42/44 chainrings, 165mm cranks, and a 700x25mm tire.
/I'm not trying to hate on your build, I'm trying to understand the "why" behind it.
