Dt 240 single speed with solid ratchet

Stupid idea time. If I got access to a CNC, and made a single piece that is the same dimmensions as the two ratchets engaged (or probably a bit longer axially, to avoid using the springs. Just have a solid block connecting hub body to freehub body), and used it as a fixie, what happens when backpedalling?

On the one hand, I could see the ring held in the hub body wanting to unscrew, but with the wheel in the frame, it shouldn't have space to move?

The plan was to have a 5 minute swap from single speed to fixed. (avoids me buying Paul's fixed hub and lacing a new wheel, and the possible rotor alignment nightmare I might get into, if the two hubs don't have the rotor face at the exact same position)
