    Sure can, as most of us could -- if only we hadn't better things to do.
    Seriously, I am working in a encoding proposal (vexillological technical
    symbols) and there's a handful of symbols which could be encoded as
    "previously existing symbol" + "combining large X overlay". (These
    symbols, BTW, are used in text, not only in pictorial, diagrammatic and
    tabular presentations.)

    From the top of my head, I could refer hermeneutics and text revision in
    general -- but that might be outside the plain text domain. (I'm quite
    sure hermeneutics is best done with mark up, BTW.)

    Of course. I was just commenting, not presenting a formal proposal.

    Hm, I'll have to update my UniBook database.

    All in due time... ;-)
