Orbit of a double planet

In a system where 2 planets of similar mass are orbiting around a common barycenter, would the following configuration considered stable on the long run?

• They orbit at 1,6 AU from their star
• The star is a F8 and is 19% more massive than the Sun
• One planet is the same size and mass than Earth, but the other is 10% more massive
• They are located roughly at 90 000 km form their common barycenter
• They are tidally locked to each other
• Their double planet system is tilted at 25 degrees, so they can have seasons

Is it flawless?

Note that the concept is not mine (source) but I want to know if it works.
