I suspect that this would be very difficult. As you may know, the Free energy (del G) involved in formation of MgO will be much more negative than that for the reduction reaction(Since it burns even at room temperature - which is a clear picture of the stability that Mg sorts to, while getting ignited). So, this means that MgO is thermodynamically much stable than Mg and even H2O. Hence, we whould definitely be sticking on to a catalyst. But, I suspect the efficacy of a catalyst to jump over such high energy barrier. It will not be easy even with a catalyst. High temperature might post other problems like explosions and excitations. However, I do not like to close the door that it cannot be done, as I personally do not trust in irreversible reactions.
