The same thread was held on the Essence Reaver page, and the final dictamination was that in no way ER would be able to "balance" Muramana's consumption. At best, it will reduce it a little bit.

Plus, I'm pretty sure ER doesn't takes into account any physical damage from on-hit effects (Muramana's toggle, BotRK's passive, Sheen/TF/IBG's Spellblade), only the damage from your AD.

Still, it helps out either minimizing your mana consumption when toggled-on (As said), or helps it regenerate back when toggled-off as well; so it is still a worthy combo for AD's.
