I think ur alternative itinerary is perfect. But you can make a bit change to enjoy the journey :
Mar 4 : Go to Hularhat by bus and take the Rocket to go Barisal. The rocket starts at 12.30 p.m and reaches Barisal at 6 p.,. So, you will get the chance to take Rocket trip some hours in daytime. In worse case, if you dont get the Rocket, take small launch to Barisal.
Mar 5/6 : In fact Kuakata is not worthy for only 1 day. Because it takes more than 5 hours to reach Kuakata. If you start 8 am from Barisal, you will reach around 2 p.m and only few hours to see Kuakata. Because next morning you have to take morning bus to reach Barisal before evening.
Better : You pass 2 days in Barisal, through visit a village, taking Barisal/Bhola/Barisal boat trip.
If you need any explanation, please feel free to ask here.
