It should not hard to write a command for case 1 (called \setcommand for
example):
\def\setcommand{\@star@or@long\set@command}
\def\set@command#1{%
\begingroup \escapechar\m@ne\xdef\@gtempa{{\string#1}}\endgroup
\let\@ifdefinable\@rc@ifdefinable
\new@command#1}
I just copied the code from \renewcommand and deleted few lines.
Since I'm not a TeX wizard I'm not sure if the above code is entirely correct.
