Adding Lores in an event

Hi all! While browsing around for different event-related subjects I came upon this old post:

https://www.ff6hacking.com/forums/showth...hp?tid=903

In it, Angelo26 shows a neat way for us to change the event code 8F that normally gives Cyan all of his Swdtech abilities into one that can teach characters Magic spells in an event. Pretty cool stuff! I tried it and it works like a charm. I guess it takes advantage of unused code in the game that performs the task but didn't have an event command associated with it.

My question is, can this be done with Lores instead of Magic spells? I tried by performing the directions from Angelo's post and using spell index 90 (Blowfish) as the spell to add, but it didn't work. Does anyone know another way? 

Here's the code the new 8F command points to when you make the changes in the aforementioned post (if it helps). Unfortunately I don't know any Assembly to understand it:
