Depends on how different they are, of course. The bullywug croaker from GoS is similar to the standard bullywug, but with more HD and two special actions. That's pretty easy to put in a variant sidebar. But the bullywug royal has more HD, save proficiencies and skills, and new traits and actions; it'd probably be wasier to give that its own statblock.Hey, if instead of two different monsters per page, we could get two to five different variations per page I'd be okay with that too.
I also think stat blocks have a lot of unnecessary repetition that could be cut while keeping clarity and leaving more room on the page.
I've struggled with this when working on PDFs in the past......some people want to print out the monster, and want it all in one long block, over and over, even if there isn't much difference. That tends to add (to me) unnecessary bloat....Depends on how different they are, of course.

Put another way: there's no way I'm going to use more than a half-page of combat info in a single combat. If it has more than that, some of it is hiding the info I actually need. (cf 4e combat stat blocks)(my main thing is I think stat blocks and monster entries should be much more compact, two per page is a good thing to aim at in my view, less is more - let specific settings or adventures tell us about more specific and detailed stuff if relevant)
Speaking personally, I would revise the heck out of this. I don't know if this is just a mockup for discussion purposes, something from a product, or what, but some of the changes I would make...So here's a (very) rough mock up of a monster entry (so ignore grammar issues; the text is just placeholder). What things do you want included beyond the typical stuff? A rumor table on what PCs might know about it? Behavior/combat tactics? Ideas/Flaws/Bonds?

Yes, variations appreciated! The Monster Manual does this to a degree (variants in sidebars like Mind Flayer Arcanists and Psychic Gray Ooze), but could offer more.Hey, if instead of two different monsters per page, we could get two to five different variations per page I'd be okay with that too.
