Default [Q] Switching internal with external memory on a Hisense Sero 7 Pro (Taktik ROM)

I've been trying for around 3-4 days now, playing around with custom ROMs and such, trying to switch my internal (8GB) memory with my external (64GB).

I'm currently using the Taktik ROM, and there is no vold.fstab under the system/etc folder.
I've also tried things like scripts that are executed, mounting the int_storage versus the sdcard1. However, upon looking, the internal storage on my tablet is called sdcard, and the external is called sdcard1, so I tried modifying the script, replacing int_storage with sdcard. This still claims that there is no file or folder found.

Is there app or script that will do this?
