I think it would be better than a real theremin, something more like the tannerin. If the faders were accurate enough that is.
It would have the advantage that the performance would not be affected by people moving close to the antennae.
Now that a lot of laptops have touch screen it could be feasible. I'm running renoise on an old windows 10 tablet. Its nice.
