My version would be:
George Harrison, the best Beatle, composed clever, well-crafted songs with such originality.
b) has parallel adjectives that work. a) has mixed a noun and adjectives in the same phrase which is awkward and non-parallel.
a: Such originality, clever, well-crafted songs, George Harrison was the best Beatle. This one doesn't work.
b: Such original, clever, well-crafted songs, George Harrison was the best Beatle.
However, I might add with there:
With such original, clever, well-crafted songs, George Harrison was the best Beatle.
Now, for c, the one below is a possibility:
c: Such originality! Clever, well-crafted songs, George Harrison was the best Beatle.
OR
Clever, well-crafted songs, George Harrison was the best Beatle—with such originality!
The em dash should be longer than the hyphen but my computer won't do that.
