One comment (just based on some reasonable amount of sheet metal fabrication experience although I won't claim to be an expert). The final bend in the vertical plane would require a specific length punch to fit inside because of the very small gap (the die could still be full length). If you opened that up so that a full length punch of some thickness would fit then (I know 1/2" would work but possibly 1/4" are available over the length of the flange) you could use standard tooling on any press brake.
