I haven't examined an auto alternator with that in mind BUT a squirrel
cage motors is a very very specialised beast indeed, optimised to
achieve the rather interesting dual task of exciting the rotor and
applying a rotating motive field to drive it. The rotor excitation is
achieved by the slip frequency field whereas a brushed DC slipring fed
field is  mechanically vastly vastly* different. May be able to be
made to rotate but I'd doubt it would be able to be made to make much
power at all**.
