Sure. 18x18* mainly contains CJK characters. Writing system of
CJK characters is different from European ones and it doesn't have
a concept of baseline. (Of course CJK characters have their own
concept of beauty on the arrangement of characters.) The reason
why CJK fonts do have "baseline" is that fonts must have it (because
mechanism of X fonts was developed in European language world). Thus,
I think we can determine the "baseline" of CJK fonts so that we feel
convenient.
Anyway, 18x18{ja,ko} is intended to be used with 9x18. You say
"it's slightly annoying *only if* you mix ..." but the main usage
of 18x18{ja,ko} is mixing it with single-width ones.

Changing descent and ascent of 18x18{ja,ko} to fit with 9x18.
Since 18x18{ja,ko} are fairly new and I think it is not too late.
