Another aspect is that Sirius is already a binary system, made up of Sirius A and Sirius B, a white dwarf, which are pretty close-up. If we include the sun, we'd have a ternary system. But probably that's not too relevant. Anyway, AFAIK it's all at the level of hypothesis, Cruttenden is basing his just expounding some archaeoastronomical principles, which need hard evidence. He says that if the solar system velocity is far higher than believed, then Sirius might be at the proper distance as a companion star. But it's still a hypothesis.
