My take on it is this: All bleaching does is to re-cycle the previopusly reduced elemental silver back to the salt, which can then be redeveloped back to an elemental state by a developer with a different reduction characteristic, in your case, a lith developer.
After the post bleach developement step, stop, fix, and wash, or optionally tone as you see fit. I can't see how things would go wrong- just process as you would without the bleach step
You do need to wash some bleaches to clear them, and some with a post bleach clearing bath, but I am pretty sure you are up on how the different bleaches work. There is the possibility that any residual bleach could cause a toner to act differently.
