With the X-Men home, who should be MCU-ized?

If I wanted to go the short route, you akready know the answer...

Also, that theme NEEDS TO BE USED IN THE MOVIES.
If we start with the Original 5 (Angel, Beast, Iceman, Marvel Girl, Penis) then, we'd need something that calls back to the original costumes. But at the same time pop, because we don't want the Singer biker suits again.

For Cyclops the inspiration for his costumes should be the X-Factor blue and white costume, the Jim Lee Costume, and the Astonishing costume.
I see him starting with a yellow and blue outfit based of the blue and white costume, which would be the base design for the OG5. (Minor alterations for each member) like say, Cyclops having the outfit in Blue and gold with a red trim on the X. Once graduated, Cyclops's outdit should be the Astonishing suit, minus the skull cap, with the Jim lee Belts and bomber jacket.

For Iceman his "first class outfit" is similar to Cyclops, but instead of blue and gold it's blue and silver with gold trim on the X. Very important:
No skull cap. Once he graduates, he forgoes the uniform and uses whatever he's wearing, seeing his ice armor covers his body... but for the mandatory Suited up X-Men scene, he'd wear basically a wetsuit similar to his first class outfit... and a pink Hawaiian shirt unbuttoned, because screw the rules.

For Angel, his outfit would be light grey (closer to white) with the blue X and gold trim.  His outdit has a half face mask with a golden trim on top. (The "halo")
 Once he graduates, he uses the iconic red and white outfit. No skull cap.

Beast gets an outfit similar to Cyclops, but in blue with black on the X and gold trim. The only huge difference would be the black Wrestling trunks on the outfit. And that the suit would look tattered at the forearms and shins.
Once graduated (and furry) Beast uses a blue and black Wrestling singlet and a lab coat. (I want to go full trunks, but this is a little compromise with the FX people.

Marvel Girl gets the same outfit in green, Gold and blue trim. Once she graduates, she gets the Jim Lee Costume, but some of the piping on the costume has subtle references to the Phoenix suit.

If we were to go with a more modern roster, skip the first class suits, and go for the graduate suits.

If we were to add Wolverine a more "Military" version of his outfit could work... maybe taking elements of the tan and Astonishing outfit.  Mask is OBLIGATORY. Can be justified by claiming it has retractable lenses to protect his more sensitive eyes and ears from things like Flashbangs. Also has a built in comm that works at frequencies too high for normal humans, but Logan can pick them up.

If we were to add Storm, well... Jim Lee Costume with some piping that makes reference to her black and gold outfit from the 70s.

Jubilee:
Civilian clothes... yellow jacket and shorts... nothing else is needed.

Gambit: trenchcoat is obligatory. And approximating the Jim Lee Costume is a must.

Rogue would be a tough one... and the outfit choice would depend on whether they do Carol or not.
If Rogue starts in the Brotherhood, then civilian clothes reminiscent of her 81 suit. If she absorbs Carol, then a Cap'n Meh Vel-ized Jim Lee Rogue Costume. If she obtains her flight and strength from someone else, then the Red and blue outfit from the early 00s.

I'm not going to do this with the F4, since the answer is classic suits.
