Not sure this is the best solution,

Definitely not.

Removing a primary key and recreating it will break the database referential integrity.

BTW reusing the gaps in the primary key, as the OP wants, is not the smartest move either. I know a couple of methods to achieve that, but I also know half a dozen reasons not to do it. Therefore I'll keep the method for myself.

In the meantime, I will just suggest leaving the primary key alone.
