Depends on the environment, but high risk of Mg corrosion.
There are special coatings used on Mg because it corrodes in many situations.

Generally, when two different base metals are in contact (or close) with each other in the presence of an electrolyte, you can expect galvanic corrosion. The fact that one element is soluble in the other isn’t typically the cause of the corrosion.

The junction just makes it worse.

To use that combination you'd have to be 100% certain that no salt water is around.

Honda used magnesium covers on their aluminum motorcycle engines. The magnesium water pump housing on my 1987 CR250 is mostly built out of Red Hand now. The external covers held up fine but even small amounts of water in the gearbox from the water pump leaks caused pitting on the insides of the mag covers.
