No, Sephiroth is so strong because he is the only one who can control his alien cells, so only because Cloud has JENOVA-S-cells it doesn't mean his children can be as strong as/stronger than Sephiroth. Almost everything about the cells can be explained, but a few things are not 100 % logical, because after all it is a fantasy story and not everything in Final Fantasy has an explanation which is 100 % logical. But the point is, Sephiroth's mind became stronger and stronger. He was able to resist the lifestream and to absorb the ancient's knowledge to become even stronger. So his mind became the strongest of all and so he was (or is) able to use JENOVA abilities like psychic power like levitation/flying or reading minds and memories, shapeshifting, creating illusionary worlds, manipulating JENOVA cells, regenerating/reuniting himself, et cetera. So even if it works and Cloud has children with JENOVA cells they must be stronger than Sephiroth's mind to be like Sephiroth and to be able to use the abilities. And after all Sephiroth has become evil because his life was nothing but a lie. Cloud's wouldn't lie if his children ask why they are so special.
