No, because the kanji that is pronounced "yoshi" in his name is this: 吉. It means good luck, joy or congratulations, and the Washuu always add it to their name when they recieve a position of Bureau Chief or something, Matsuri was gonna do it, too, and Furuta and Yoshitoki did it, as well. The kanji can also be pronounce "Kichi", which is how "Kichimura Washuu", Furuta's name while he was Bureau Chief, came to be.

Now this is the kanji used in Hide's name: 良. It just means good, skilled or pleasing, and is a different kanji. So basically: The Washuu just add the kanji to their name, probably as a ritual, and to say "congratulations on the promotion", while Hide was basically just called "Hideyoshi" from the beginning. The namesake is very positive, as "Hide" (秀) means excellent, and as said, "Yoshi" (良) means good, pleasing.

You can also write Hideyoshi with the kanji the Washuu use, but this is not the case here, so the two are probably totally unrelated to each other, so the theory is probably debunked, and we know that Hide has been with Kaneki since he was a little kid, and being related to the Washuu would either make you a ghoul, and since Hide was shown often eating totally normal human food, even when alone and no reason to do so as a ghoul to put up a front, or you'd be a half-human, meaning you'd either be in Sunlit Garden, or having V hunt you. Hide was in the Washuu's way for his knowledge of what was happening, and he never really displayed any high physical abilities the half-humans have, he probably picked up his ninja skills from his life as Scarecrow.

So there you have it, a long explanation why this probably is not the case.
