At this date, Latin alphabet was definitely in use everywere, totally integrated and runes a past thing. I don't see the system he developed being used by other scholars, or even institutions without a complete collapse of litteracy.
Well, Romania completely converted from the old Romanian Cyrillic Alphabet to the Latin Alphabet in the 1860's, and the Cyrillic alphabet was strongly implanted in that Orthodox state. I couldn't see the impossibility of Runes in Sweden, though their success in Sweden could be temporary or limited for vernacular use or use in rural areas.
I try again, then:I like where you're going with this unfortunately I was not able to see the runes.
