Morondava - Kirindy Forest public transport / taxi

Hello, I am planning a trip to Madagascar, my itinerary would be 3 blocks: 1) with driver - fly to Kirindy - Ranomafana - drop off at Andasibe (or other way around) 2) Andasibe 4 nights. 3) Ankarafantsika 3 nights I would to fly to Morondava, then find a suitable transport to bring us to the forest: This could be a local taxi or a bus, do half a day + night tour, another full day and another half day, and then have a driver for our Ranomafana/Anja->Andasibe leg to pick us up at Kirindy, stop at the baobabs for the sunrise and leave eastward the next morning. I know most people spend less time in Kirindy, but I am a wildlife enthusiast and willing to spend extra time. It feels pointless for me to pay another 2 days for a driver and a car, when in Kirindy we are effectively on one spot (is that indeed so?). Could you please advise, if such a plan is feasible and how to go around it? Thank you.
