Naw, I imagine they would have to deal with the huge aftermath. Etienne is a dominant Omega and the heir to the throne, but only because the public and the King believe he is a Beta. Rishar is a dominant Alpha and sought out to become the successor to the throne. If Rishar were to additionally declare that he is going to take the throne, but with Etienne as his "Queen" it might actually work. Tho all of this will likely not be smooth sailing ╥﹏╥
If I remember correctly his mother is away too so when she's not in the capital he should walk around with his original eye color
Can't the Emperor make a ball or event in hall and ML brought MC with his natural eyes. Then, ML explained all shts that happened to MC. So, it's like social death to MC's mom.
