Multiple MX records for backup purposes

Let's say I have a domain and email accounts at Runbox and Fastmail. Both Runbox and Fastmail forward the incoming emails to my Gmail account.

Is it ok to put both runbox and fastmail's MX servers in my domain DNS? (the domain is registered and activated both at runbox and fastmail, the same email addresses under this domain are set up at both places)

If I have mx.runbox.com with priority 10 and mx.fastmail.com with priority 20, will fastmail server be able to receive and forward the incoming emails if runbox is down?

Is it any conflict if I put the mxes from two different email service providers?

And to make things MORE complicated, I plan to use mailgun as smtp server
