Buffett has repeatedly said that insurance float is better than equity capital......
I’ve ballparked float value at 1.3X equity.

IMO your understanding of float is flawed. When Buffett said float is better than equity, he meant that Berkshire would have to sell additional shares to raise equivalent amount of equity as float which makes such an alternative far worse for shareholders. He didn't mean that you could just take float and slap a multiple > 1 and simply add it to shareholder equity on the balance sheet.
