No. In my interpretation (about what Isshin said) only those with power compare to them can sense them. What Aizen said can be throw off as God-Complex lectures. Neither of them had the power to destroy Soul Society, hell, not even Seireitei or Karakura Town. Monster Aizen's fragor didn't even reach Karakura Town, therefore is way below Shikai Kenpachi's meteor busting feat. Even Aizen who got "stronger" was fodder to Yhwach. He survive long enough for trapping Yhwach under KS during the first invasion.
