5 kage Temari adds shields to your Wind and earth ninja, and deals some decent damage, as well as chasing off of main clones and causing repulse (which most empress lineups love). Simply replacing Your healer with a Temari 5 Kage's is probably your easiest switch.
My last Empress lineup I used was Hinata+Kurenai+Asuma. Asuma unfortunately misses out on buffs from the rest of you (use clones as well for soft-body shields, not queen momentum) so you tend to need to shield him with kurenai turn 1. The reason for using him is when you hit 70+ chakra his mystery is free and has no cooldown, so you can fill the gap while Main is cooling down with a mystery and Hinata chase every turn.
But yeah, work on adding Temari 5 kage into your lineup, she's awesome
