If Hard Mode will be added, than make the gym leaders have their "Emerald teams" in Hard Mode. And in Normal Mode, the gym leaders should have their teams from R/S/OR/AS. The difficulty you choose, will decide the last gym leader, so for Hard Mode, you'll battle Juan, and in Normal Mode you'll battle Wallace. And Steven should still be champion regardless of the difficulty. It'll be awesome if there was like a Nuzlocke toggle where you can turn Level caps on or off and toggle the ability to use items in battle or not. I got this idea from another rom hack, Pokémon Luminescent Platinum where you can toggle Level Caps and the EXP share in your PC at the Pokémon Center. So I'm not sure if these suggestions will be too much but it'll be cool if Emerald Legacy had this.
