Turns out this is pretty easy to activate. The only hard work technically is adding one tiny bit of extra data for the fade screen, moving the pointers and then reassinging the extra pointers. All of this data still exists within the ROM and is even translated as seen, just goes unused due to it being skipped.
I can see why they cut it though, having all that extra data on the character and then this HUUUGEE mass of text. It HAS to wipe the entire data before hand otherwise it will not work properly. Though, really interesting to see all of this working fully.
