Doubling down on the request for this from us RV-12 people who live in a perpetually weight-constrained world.
The output of the standard Rotax 912 ULS electrical system is limited at 15 amps, so a backup with significantly more power would be incredible.
An even better solution would be a mount which interfaces with the currently-empty vacuum pump mount on the back of the gearbox, since this would avoid having to modify the cowling to accommodate the belt drive. On the RV-12, this would need to take into account the pitot connection block, but that can probably be solved with a unified bracket which combines both functions.
