biblatex numeric style with author last name?

Question

I am currently usign the numeric style in biblatex. This gives me the obvious result of [22] when I call \cite{Someone}. I would like to stick to the numeric style but also include the last name in the citation, for example something along the lines of: [(Someone)22] or (Someone)[22]. My question is two fold:

1. Is this citation style in any way common? I would probably distance myself from it if it is too far from current standards.
2. How would I implement this? I assume the trick lies somewhere in \DeclareCiteCommand, but I don't know where to start.

Answer 1

We can define a new citation command (analogous to BibLaTeX citing style)

\DeclareCiteCommand{\morecite}[\mkbibbrackets]
  {\usebibmacro{prenote}}%
  {\usebibmacro{citeindex}%
   \printnames{labelname}%
   \setunit{\addcomma\space}
   \usebibmacro{cite}}
  {\multicitedelim}%
  {\usebibmacro{postnote}}

If you insist, you can replace the normal \cite

\DeclareCiteCommand{\cite}[\mkbibbrackets]
  {\usebibmacro{prenote}}%
  {\usebibmacro{citeindex}%
   \printnames{labelname}%
   \setunit{\addcomma\space}
   \usebibmacro{cite}}
  {\multicitedelim}%
  {\usebibmacro{postnote}}
