James Franco and Seth Rogen -- We're More Vogue than Kim and Kanye

James Franco and Seth Rogen have improved the Vogue cover with Kim Kardashian and Kanye West ... although they missed one slight detail.

Rogen tweeted the cover -- we're guessing it's photoshopped -- with Seth playing bitch. We might add, not an unattractive bride.

They almost had us fooled ... but then we looked at in the vicinity of the ring and, well, you don't get that from a Hawaiian vacation.

As you recall ... the duo hilariously spoofed Kimye in November with their music video "Bound 3."

It was bound 2 happen.
