Just a point.

The core of the Jaguar that handles the large current is the N-Channel MOSFET bridge.

That bridge has a high side driver to make the positive voltages above the input voltage required to actually turn on the high side MOSFETs (they aren't P-Channel so you need this trick).

If the bridge had P-channel high side MOSFETs you'd have more issues (I think I remember the older beige Jaguars being like this) because the match between the P-channel and N-channel MOSFETs is not great and P-Channel MOSFETs tend to be really easy to utterly destory under bad conditions.

The bridge itself could be rigged to survive inverting the positive and negative being reversed. Hence you wouldn't need a 100A or more diode (you best not use a 60A diode on a load that reaches 60A unless you like bad things happening).

The rest of the electronics, including the Stellaris could be powered from a simple bridge rectifier (which would make the positive and negative on the other side *always* the right polarity...if you don't mind loosing 1.4 or so volts DC on the input to the local power supply and I doubt based on the existing schematics it would).

In short I believe this could be done and NOT have to deal with high power parts to do it.
