Eyugh.  Nope.

% foo='This prompt "contains" `surprises'\''?'
% vared -cp ${(q)foo} stuff
This\ prompt\ \"contains\"\ `surprises\'\?

To automate probably better off with

vared_prompt() {
   emulate -L zsh
   unsetopt promptsubst
   vared -p $1 $2
}
vared_prompt 'The literal prompt' the_variable

pws
