It depends on why you'd want to do this.  There's no way to have zsh
load/use the readline library, but if you install "rlwrap" and explain
what you expect to happen, there may be a way.

Brute force would be "rlwrap zsh +ozle" but I can't speak to
unexpected side-effects.

I would definitely second Pier Paolo Grassi's recommendation --- vared
is the way to do this in zsh, as he said.  The simplest form is:

var="This is prewritten text"
vared var

pws

Can you describe your use case? Why do you want to replace zle with readline?

Generally, zle is more powerful and can do anything that readline can plus more.
