This works:

f() { MARK=0; CURSOR=$#BUFFER; REGION_ACTIVE=1; }
zle -N f
bindkey '^T' f
echo foo^V^Jecho bar^T    # In this line, ^X means to press Ctrl+X

It doesn't work in some other cases.  It works when $BUFFER is
multiline and $PREBUFFER is empty, but it doesn't work when $BUFFER is
single-line and the previous content is in $PREBUFFER.  You might be
able to simulate that with 'P' ranges in region_highlight and
overriding widgets that operate on the region, but it might be easier
to just use edit-command-line.
