Well you have to consider that Bt-toxin is 'originally' (it all came
from some RNA soup, way back whenever, or whatever) from a bacteria,
hacked to work in plants.

So I think this is more a question on horizontal transfer mechanisms,
which we know something about, and also about gene-shuffling. You'd
need to pick up the Bt from plants, then keep it around long enough so
it would shuffle some way or another to a working promoter...
requiring also it wasn't otherwise broken in the shuffle.
