So, Gideon Zhi posted an update today here: https://agtp.romhack.net/pantheon/index.php?topic=757
It looks like he ended up using the tiny French font like I did. 
Yeah, this has been on my to-post queue for the last month or two, but it's kind of languished behind the Masoukishin releases. I've been trying to make a post at least once a week, usually on a Monday or Tuesday, and this happened to be this week's. (There are only three left; one's an announcement, one's progress that I want new screenshots for, and one's, well, you'll see.)
None of my work is actually based on the French version; the 4x8 font in my screenshots is actually done programmatically (though it might be the same graphics as the french one, idk). I held out for a vwf from other people for *years* and at this point I'd rather just have the 4x8 and something releasable than nothing at all, and I'm not confident enough in my z80 skill to write an actual vwf.

It's still a good ways off though, and I'm probably a few months away from being able to devote any meaningful time to it.
