I honestly feel for that bike thing you should just have mahin in between the 'big badass dudes' just being adorably squished or something, and not change the whole idea of godzilla/optimus too much, but dats just my idea
like, maybe you could have mahin kind of secretly and adorably hidden in several of your pictures, like a where's waldo kind of little easter egg, if applicable
also i tried to make it obvious that #3 was the one i wanted the most once i thought of it, i think it'd be the greatest thing. like, mahin just chillin' with a bag of cheese poofs (or the flowery mimiga equivalent) on a big chair, watching a big old-school tv with a wonky antenna that had freakazoid riding pinkie pie, pinkie pie either being a normal pony with a pink rainbow in her wake or the nyan cat's head/legs/tail replaced by hers or something idk you can think up something clever!
i-i mean i-if that request is okay with you a-and all... *looks away while shyly poking his forefingers against each other*
