I sing in a cover band and after a few rehearsals, we decided to downtune all the songs (Judas, Maiden, Rainbow, Queensryche...). At the end of the set, I was very tired and it was hard for me to sing consistently. With the downtuning, the improvement has been almost miraculous for me. I think it would be also great for Bruce (he sounds great in 'If Eternity Should Fail'!).
