Yes, many.
1. I doubt Einstein chat bot can create API call into guest messaging API.
2. Authenticated Messaging is probably impossible or highly unlikely.
3. Context from bot (transcript) requires a JSON array, so most likely not probable.
4. Einstein could not use GCx Knowledge Workbench or enterprise KMS like Shelf.io
5. Passing skills and routing and user information would be through a single attribute.
If it were me, I would go with a Boy Connector to Einstein. Check out the Blueprint for Watson and do as the Chinese R&D do - replicate and duplicate.
