nekmo seems like a fine choice but also see no reason not to bring seeker into it as well, 2 tm can produce a lot of dmg if you work around it right, or even high khatun as lead role with a 2ndry tm booster can produce some nice early fast damage.

high khatun lead, nekmo, kael , ronda drath for now maybe? 

edit : infact nekmo just looks pretty much the same as what khatun can give you but more, so id say neeko lead, seeker, kael, ronda,drath instead
