Other variants
deviantART user JapanYoshi likened archaic Witch Runes to blackletter/fraktur writing and modern Witch Character to serif, and attempted to make a "Sans Serif" variant. He only supplies a pixel art sample, but by far the most simplified variant for better or for worse.

Notes
A
B
Based on Modern B, rather than the Archaic version, when concentrating on speed. This may clash with E and M.
C
Borrowed from Prima's variant.
D
E
Based on the Archaic version of E. The crossing stroke is more distinct than with the modern version.
F
G
Tentative. The modern G Witch Character feels more natural for handwriting, when compared to the inverse curl required in the archaic version.
H
I
Shape taken from modern I. Both modern and archaic share same features, modern is more fit for handwriting in this one.
