I'd imagine it be possible if he has enough mana and the magical know how.

If he became an Incubus simply through mana corrosion like traveling through a Demon Realm or eating a fair ammount of Demon Realm produce then he likely try to create a familiar if he was having trouble finding a Mamono partner (however unlikely).

If he were turned into an Incubus via making love his Mamano wife/wives then he simply would have little to no reason to do so, not to mention that his wife/wives would try to discourage it as it would mean another rival for their husband's affection.
