Effluvium doesn't work like that. She has to rely in other methods to alter herself in that manner. The substance is meant to decay corpses and make the living dead/undead.

Any effect on a human womans figure that is afflicted by Effluvium isn't caused by Effluvium itself, but by the Demonic Energy that they gain as they are turned into undead mamono.

Of course a mamonos figure will naturally shift towards her husbands ideal and there are plenty of spells and magical items that can alter a womans figure available.
