Then maybe you're missing that there are no non-core magic types?

Just because there aren't, or at least, so far I haven't located any, doesn't mean there couldn't be. Otherwise there would be no point it the '~' magic type. See item 44 in the third table below Perlguts#magic virtual tables:
~ PERL_MAGIC_ext (none) Available for use by ext
+ensions
For my particular purpose, substr magic would work perfectly so long as I can adjust the offset/length appropriately.

Interesting! My last post was wrong. You can add ext magic using sv_magic (no vtable) or sv_magicext (with vtable).
Then I guess you missed "The extra fields only have meaning to the associated magic handlers". That means it's entirely up to you what you put in them if you have your own magic.
I wonder if each variables with ext magic has its own virtual table pointer.
