You loose LPA (low power audio) with viper4android. Are you sure it's a) worth it and b) it won't work with the already installed busybox version?
I don't know if the rom uses lmza somewhere else, but for me it sounds unlikely. It would probably be worth a try to uninstall the dual recovery (delete /system/bin/chargemon and rename /system/bin/chargemon.stock to chargemon if there is no uninstaller) and try updating busybox. Backup before, no guarantees and do it on your own risk though. If you want to install a single recovery you have to be on unlocked bootloader afaik.
Another solution would be to compile (or nicely ask the creator of dual recovery) the latest busybox with lmza support by yourself.
