Anything is possible...
But think for a minute what I mentioned earlier in this post.
If direct read will be possible in near future, it is only 1/3 of equation. The strongest point of RTs are to be able to produce variation/generation. To make style for arranger sound the "best" (which is also subjective), it would have to be modified significantly to sound identical with Customer "A" and Customer "B". Meaning, all the parts would have to be generated in advanced and the better ones selected and mapped to corresponding arranger section(s), but at the same time they should be user editable as far as particular section / instrument regeneration. So not only it would be possible to regenerate particular "included" instrument track, but to substitute it with RT from another style. And the last 1/3 of equation is very specific interface aimed for live playing.
I am not trying to be a thread buster, I actually think it's a great idea and I support it 100%, but it would require different thinking and muscle power.
