Not sure if this counts (as it was hardly a proper attempt at transliteration) but within the Transformers fandom, there was an artist by the name of Patrick Lee working on the Transformers comics who became particularly notorious for being, well, an arrogant twat.
He decided it’d look really cool to “transliterate” his name in katakana on his website. And his super-cool transliterated name was? “ミチヤメノテヒ フナナ”. Yes, Michiyamenotehi Funana. Clearly the sad result of using a “katakana” font that switched Latin characters with kana:
ミチヤメノテヒ フナナ
PATRICK LEE
And many lulz were had.
