Sorry, I cannot agree with you here.
What is a "blackboard bold semi-colon" meant to mean?
How is it different to a normal semi-colon?
If there is a different meaning, where does this occur
within existing literature?
Blackboard-bold is meant as a collection of symbols (that happen
to resemble ordinary letters). It is *not* meant to be an
alternative alphabet used for constructing words and sentences.

No.
A "complete math expression" should never be all blackboard-bold.
Individual symbols within a math expression may be blackboard bold.

Fonts can contain symbols that have not gained acceptance
in any particular field of mathematics.
If you use these symbols, then you will certainly
have difficulty trying to get your work published,
in a journal, ...
... or electronically on the web, since there is
no available Unicode code-point for such a symbol.
