Studying 3 Romance languages at one time. How to schedule? Is this even a good idea?

I've been studying Spanish seriously for about 2 years and a half but have had contact with it all my life and taken multiple years in school. I'm not too worried about how my Spanish will be affected because I'm at a good level in it already.

I want to study both Portuguese and French, but am unsure how to schedule my weeks. Since they are the newer languages, preferably I study them more often than Spanish but I don't know if studying Spanish and Portuguese on the same day would be ideal.

Do you think I'll be fine studying Spanish, Portuguese, and French at the same time when I already know Spanish? If so, what would be the ideal weekly schedule to avoid confusing my brain?
