Innovative and Different (from the couple dozen children's books I've read)! Wildly Popular (with the neighbor kids)!

I have recently published a new children's book format I call Coloromics. A coloring and comic book format published as one book. Since the release of the Coloromic Books the featured cartoon characters have generated a great deal of readership popularity amongst kids. A week ago a professional critic's review was featured in a national comics and kid's entertainment magazine and my book received a 3 star rating. The review stated that my written words displayed a subtle wit and that my artwork brings charm to the pages. The story is simple but can be read over and over again. The story is fun and entertaining and evokes memories of characters such as Bugs Bunny confronting Elmer Fudd and Yosemite Sam and ultimately getting the upper hand over his protagonists. What would be the best course of action in regards to submitting an already popular book published in one format in the hopes of publishing the same storyline and illustrations inside a children's picture book? The existing Coloromic Book consists of 32 pages with covers. The critic's words appear to describe exactly what one would hope for regarding a children's picture book review. Do publisher's accept content that may already be available in another format for kids? Should I send a manuscript with the illustrations or just submit the published book and attach the critic's magazine review?

Some pertinent facts:

• The comic book industry is kind of a separate thing, and the opinions of a critic in that industry will hold little weight with a children's book editor.
• Comics that are black and white and meant to be colored are, while not common, not groundbreaking either.
• The industry is having an extreme doodle-activity-book moment, but do not confuse that popularity with the less exciting activity of coloring in someone else's art.

Do not send a publisher your previously published (or was it self published?) book. If it was published, then did you not sell the publication rights to the publisher? If so, they belong to the publisher now, fyi.

But let's say the rights are in your possession. If you think there is an opportunity for reuse of the material in a NEW format, then you need to be very clear with the people you are submitting to WHAT that new format would be. That's the thing to bring across, and sending them a copy of the OLD format will do exactly the opposite. (Do, of course, be clear with them about the other edition of the material that's on the market.)

Also, what's "a great deal of readership popularity"? In numbers, I mean. 100? 200?
Numbers that low are not "a great deal". Include actual sales figures so that the editor knows just what you're talking about, or she'll assume you're exaggerating like crazy.
