What would happen, if?

What would happen if Trump is impeached and "convicted" on frivolous charges, his removal is ordered and the entire order of succession declines to step up?
They are:
Vice President
Speaker of the House
President Pro Tempore of the Senate
Secretary of State
Secretary of the Treasury
Secretary of Defense
Attorney General
Secretary of the Interior
Secretary of Agriculture
Secretary of Commerce
Secretary of Labor
Secretary of Health and Human Services
Secretary of Housing and Urban Development
Secretary of Transportation
Secretary of Energy
Secretary of Education
Secretary of Veterans Affairs
Secretary of Homeland Security

If they, loyal to the President, all smell the rat and refuse to step up, what happens then?
If the Secretary of War and Secretary of Homeland Security say no, what then? What enforcement remains.

Have a nice day.

Feel the hate! I love this. You will finally get what you have wished for. Good luck with that.
