Diego Luna Mr Fantastic?

Just recently on the Sith Council podcast, Diego Luna was asked about his involvement in marvel projects or joining the MCU, obviously Diego denied because he would be in big trouble with Kevin Fiege. But, he acted very nervous when asked this question, which has me thinking who would he play?

I had a few suggestions: Ghost Rider, Wolverine, or perhaps a Doctor Strange variant. Then I thought, "Maybe Doctor Doom?" And with Doctor Doom, you must have MR Fantastic.

I think Diego would be a great Mr Fantastic: here is a concept I made:

I think he would bring some darkness to the character, as he did I Andor. Lots of people have pitched him as a younger character. I think that Diego could bring some greatness to the character we have not seen before.
