I don't know about anyone else but my choices would be Scott, Jean, and Storm.
Yup.
Me too, and I also think when the Professor offers them that have Alex all for it, and have Scott be unsure, thinks it's a con but he goes anyway for Alex.
Then at the mansion he still unsure, but through out the movie he grows into it, and starts to become the character fans knows and love.
I know for Scott/Jean first meeting I was thinking of having Jean be extrovert, and Scott be introvert but not because he likes it that way but because he fears he'll hurt anyone with his powers he sadly can't control so instead being a jerk he acts like he's uninterested in her because he doesn't want to hurt her.
Of course throughout the movie the walls he has build eventually start to come down.
Also another thing maybe have him with the ruby quartz glasses before he meets the Professor that way it would be different from Fox's, tease his secret ties to Sinister, and later on the Professor gives him his ruby quartz visor.
I don't know these are just some ideas I had for MCU Cyclops.
Yes, ironically what Fox did to him is turning out to be a blessing in disguise, and it isn't like Feige doesn't know what they did to Cyclops or at least for X1/X2. Honestly, I know this sounds crazy but I believe Feige doing X-Men is gonna be him saying to Fox now here's the X-Men, the real X-Men.
Yup, and sorry for the long post I got carried away there.
