Well, without looking into the definition of \citep I cannot
guarantee that this will work, but /if/ \citep is a simple
one-parameter macro, then the following might suffice :

	\let \canonicalcitep = \citep
	\def \citep {\passivecolon \canonicalcitep \activecolon}
	\def \passivecolon {\catcode `\: = \catcode `\* \relax}
	\def \activecolon {\catcode `\: = \active}

(Substitute another passive char for * if the latter turns
  out not to be passive in this context).
