We have not tried this, so I can't say.

Yes. We do this all the time. So far (a dozen or two mutants) I have
always been able to design the mutagenesis oligo to either create or
delete a mappable restriction site so we can screen by mapping. It
does take a lot a staring at the sequence possibilities to find short
palindromes. It is easier if you have easy access to unusual
restriction enzymes, but so far I have been able to keep to the common
10 enzymes for all but one mutation.
