BTW has anyone done a study of the plausibility of "fused" or "hybrid" glyphs for g, m, u...?

I think it's natural to do so for two reasons... 1) there's a prevalent curve and line theme in VMS glyph shapes and 2) in Latin scribal conventions each of the glyphs you posted is an abbreviation and the loop/descender on the first two and the tail on the second one are read in Latin as "add-ons" (the glyph has two parts). Since they are two-part glyphs in Latin, then perhaps they are two-part glyphs in the VMS. They may not mean the same thing, but they are perhaps constructed the same way.

I've been trying to (statistically) sort out which ones are distinct and might need to be interpreted differently (e.g., EVA-m has three basic variations) and which ones are simply pen variations.
