The Watchtower Bible and Tract Society aka Jehovah Witnesses have been saying they discovered those same missing vowels for at least a century. Y is pronounced like J in YHWH they say.
They also can hardly wait for that New World Order to get here where anyone was disinterested in what they came to tell you at your home on on the streets will be destroyed. Then they get to pet all the wild animals who won't try to eat or kill them anymore I guess cause they all went vegetarian or something.
