A contrario, we can observe that some living structures can be adapted (within reason) to multiple scale orders. Monkeys can be the size of mice or bigger than most humans. Feline will vary between 4 and 650 pounds. Yeah there are elephant species which are smaller than others, but you don't see any of the degree of variation present in, let's say, caniforms, feliforms or even ursidae — Akanthinos

But you're severely underestimating the significance of such a change here, I think. With respect to metabolism, we're talking about two creatures at almost the opposite end of the animal kingdom. The Etruscan shew spoken of in the video has a metabolic rate of about 6 Liters of O2/hour/kg; And African elephant has a rate of 0.164 L of O2/h/kg. That's a
36 fold difference, or a difference of 3600%. More numbers: an elephant on average weighs 250,000x that of a mouse/shrew; but following the scaling laws of surface/area to volume, a shew blown up to the size of an elephant would only have 5000x more surface area by which to expel the same amount of heat: thats a
50 fold difference. There is simply no conceivable way any kind of regulation would overcome the disparity in metabolism and size. It's just fantasy.
And this isnt' even to speak of the phyisological differences. As a furter instance, an elephant's skeleton makes up about 16.5% of an elephants total weight. This is a
huge proportion - just under a
sixth of it's body mass - one that is necessary precicely in order to support the elephant's giant weight. A mouse's skeleton by contast makes up about 8% of it's body weight, reflective of the fact that it simply doesn't need the kind of supportive structure that an elephant has. And this necessity carries over into other aspects as well: the musculature of an elephant would simply never develop in that way in a creature as small as a mouse or shrew.
source (worth a read - covers the same ground as a video, possibly even inspired it. Actually, it's got a great gif of what the surface area of an elephant must look like in order to dispel the heat produced by the shew's metabolism:

).
Among the closest analogs of what an elephant might look like would be something like a mouse deer, which has a similar leg to upper body proportion to an elephant:
But notice the tiny, tiny girth of it's legs: which enable it to be both nimble, and are all that is necessary to hold up it's similarly tiny tiny weight. The girth of elephant legs on a small creature would be idiotic - without the nibleness they provide, they'd be hunted down and eaten in no time. They're evolutionary nonsense. And with respect to ears, Aug spoke of hippo ears, and seemed to forget that Hippos spend most of the time in water, which does the majority of their cooling for them, so have no need for the massive ears of elephants: in fact
another testament to the fact that form is intimately bound up in the immanent conditions which give rise to it (and the engineering of a hippo in general also reflects it's aqueous nature: it's eyes, ears and nostrils are all located as far 'up' on it's body as can be, allowing their senses to be operative while underwater).
All in all: form is only ever the product of immanence.
