Does using a virtual midi patchbay help solve the problem? Perhaps you can run Ableton concurrently with PT and patch the MIDI through to PT to trigger the relevant VI's. The required software is Midi Yoke (freeware), but you either have to disable audio in Ableton for it to work, or have a second sound card since, to the best of my knowledge, the Digi box won't work on both the sequencers concurrently unless Ableton is a rewire slave (in the latter case you cannot use Ableton to trigger PT's VIs).
