Modern?.. not to my knowledge; Dvorak could be DIY'd somewhat easily by manually moving typebars (characters are exchangeble, albeit with a lot effort, on most typewriters). Dvorak typeballs do exist for IBM Selectrics (just relabel the keys... or touch type).
An easier solution to your last question could involve the 1970-era Selectric II, which already has a built-in DAC (and OEM add-ons to e.g. turn your typewriter into a Telex printer)... which could easily interface with a USB keyboard (instead of the typewriter's onboard keys).
Maybe it would be better to have some sort of middle man hardware
Part of a reason to avoid this would be that this "friction" disuades the simplicity of just using a typewriter on any whim. If yours is not an electric model, you don't even need to turn anything `ON`.
