Why are you job hopping, if you don't mind me asking?
If a company is hiring for a senior position, then _from an HR perspective_ they want the employee to ideally stay for 2-4 years. You're at the age where not only you could retire soon, if the job gets hard then it's a permanent option on the table that an employer will need to continue to compete against and eventually will lose.
Going for high-pay contracting positions will probably be hugely effective. People will understand where you're coming from, and you might get to work on more interesting things because your resume impressively speaks for itself.
