Dr. Moreau as a tank is actually being discussed in this topic. Theoretically it could work, but if I had him, I would go attack path. Also bear in mind DF and Dr. M will overlap each others blinds, so despite being somewhat annoying, it’s not that optimal.
If I had your roster, I would try this setup:
Dr. Moreau-Gazelle-Vanda-Magni-Liana
