I don't think so, no, unless I misunderstand how "w/nocase" works.
Having case is not synonymous with being part of a casing pair: there
are lower case letters like ẗ (t with diaeresis) that have no upper
case equivalents, and the mathematical letters at U+1D400 et seqq. have
case but don't form casing pairs.

        Is it not written, "That which is written, is written"?
