Yes. You have ready a custom recovery,cwm or twrp. Wipe data/factory reset~wipe cache partition~advanced~wipe dalvik cache~go back~format sistem~go back then install zip from sd card~choose a custom rom and gapps.

Copy ROM and Gapps zip files to external SD card.

1). Install TWRP or CWM using ODIN.
2). Make a nAndroid backup (backup and restore backup).
3). Perform a factory reset.
4).Go to "install" and select the ROM zip file and gapps.
