Sho would. He almost perfectly fits the bill.
As far as I have come to understand, you have to meet three criteria to be able to heft Mjölnir (providing Thor is not wielding it himself, or forbids you from doing so):
- You have to be brave. You have to engage threats and evil courageously.
- You have to be honorable. You have to be honest and possess integrity.
- You have to be a warrior. And this does mean that, should the need arise, you have to be prepared to kill.
Wonder Woman could lift the hammer, when it crossed into the DC universe, and this is entirely logical, because of all superheroes and heroines, she is most like Thor. Honestly, if those ever became a couple... But Superman, who is stronger than she is, and brave and honorable to a fault, nevertheless could not lift the hammer. I don't know whether Batman would be able to, but I suspect he would not.... deception and mind games are a part of his arsenal, and he is very serious about not killing.
Incidentally, Captain America is capable of lifting Mjölnir and has done so in the past. The Hulk, adversely, never has... although it is possible that one of personalities might be able to. Another Marvel hero who lifted Mjölnir was the alien, Beta Ray Bill - a warrior from the Korbinite race. He signed up, along with many others, to be subjected to a series of grueling tests, of which he ultimately was the only survivor; all so he could be cybernetically and genetically augmented into the champion and protector of his people, as their entire civilization migrated across space in a massive fleet of space ships. Again: Brave, honorable and a warrior.

In any case - Sho Fukamachi would be able to lift the hammer. And I don't think anyone else could, in the Guyver universe ('Guyverse'?).
