Northern Ireland already has different laws - e.g. abortion as stated above.

It could easily retain it's own identity, the Queen and alignment to the UK over the vast vast majority of areas. Which most of them would probably vote for given the choice.

This farce is only going to push a united Ireland closer. Without bringing up who is likely to die off sooner rather than later, the birth rate is higher in nationalist voting communities than the unionist communities.

Brexit is truly an exceptional act of British Nationalism removing the objectivity of normally rational people over a huge number of issues.
