If you're on Android you could make a secondary user profile that will act as it's a different phone. I was banned too and this trick worked like a charm, minus being forced to swap profile everytime I want to play.
You mean, playing on the original app from play store with your "mod" account? If that's what you mean, you'd still have a risk of getting banned. I've tested this on my throwaway account, changing your apk to the original apk doesn't protect you from JC's cheater screening. Because you had used the mod service before you changed your apk, the hack had altered your game's code. You'd immediately have been busted the moment they check your account.
