Well as an aside, I myself when I was about 14 or so made up my own alphabet based on random glyphs i liked.

I used it to take notes in school and what not, but it was pretty simple. I did things like the thorn for th so it wasn't a direct 1->1 thing. So I could easily see #1 as a possibility. I just hope #2 is true. But its unlikely we'll know in our lifetime given that manuscripts history.
