I've seen such things done to other small craft. In the end they result on added complications and huge amount of drag. One boat I spent years chasing small leaks from the installation.
I thought about drag too, but my ePropulsion outboard generates energy from the prop when sailing, so most of the time (except when the battery is full already) I want it to drag. I'm not sure if the pod drives also generate. Regarding the chance of leaks, I would imagine that could be rectified.
My biggest concern was that if the propeller were recessed enough to not come below the skegs, then I wonder if it gets difficult to be sure there's enough flow in front of the propeller. It might require a pretty severe channel be formed in the bottom of the boat.

At what speed? SCAMPs ain't the fastest boats and IMO your assumptive average speed needs to be 3kts sailing.
The power generation assumptions of manufacturers are really greatly overstated. The minimum speed is really high. Read the fine print as in power generation mode there may be a power DRAW so if you are going to slow you are draining the battery.
Still, IMO, don't hack the boat to make it an inboard.
