So, I was trying to come up with more reasons as to why they'd spell the name with a "DX" when those letters aren't even remotely pronounced "DOX".

Of course there's the common Japanese usage of DX for video games and toys (in place of deluxe), but someone else suggested that in certain practices, DX is a shorthand medical term for either "disease" or "diagnosis", which got me thinking: what does Para- mean in the same context?
Para- as a medical prefix can mean things like "abnormal", "the involvement of two parts or a pair", or "nearby/adjacent to" as well. Which means Para-DX's name spelling can be considered a multifaceted pun;

-"Nearby-Disease"
-"Abnormal-Diagnosis"
-"Double-Deluxe"
and, of course
-"Paradox"
