Not as you describe it, no.  You could remove all bidi formatting
controls with subst-char-in-string or with string-match/replace-match,
and then use bidi-string-mark-left-to-right to solve many problems
with bidirectional display of mixed RTL and LTR text.  But note that
bidi-string-mark-left-to-right doesn't exactly wrap the string in an
embedding, it does something smarter.
