It’d be a long stretch for sure, but could produce viable foals, I think about it kinda like a male wiener dog breeding with a female Great Dane or German Shepherd
Though it could also produce horribly mutated fluffs, tiny body with huge limbs, tiny head/huge body, huge head/tiny body, my list goes on lol
Another funny detail: She failed to notice that two of them are not even seafluffs, anymore.
Hmm, I would have been tempted to replace the one with the attitude problem with a good-natured mature microfluff.
