i cant imagine anything bad happening to an engine because of to often of oil changes. the only thing that is getting used up in engine oil is the protective package (additives to counter corrosion, additives that keep viscosity stable enough across the temp range, additives filling micro cavities in moving parts) and if you change your oil soon enough you basically dropping additive package that is still good.
i'd say very slight (almost only academic) benefit for the engine vs considerable expence for you.
