I really can’t see that. There are significant numbers of senior MPs that just couldn’t countenance such a thing and they aren’t just the centrists. On the other side Farage won’t want the scrutiny and the albeit limited democracy that comes with joining the Tory Party. If you notice, it’s always been for the Reform side that Tories should join them.
Also those current MPs with reduced majorities thanks to Reform will not to be too receptive right now to any overtures from Reform, they too will want to cling to their internal democracy which they would absolutely be giving up in joining Reform. (Plus in most cases a local party mechanism that assists them).
The only way it happens is if Farage joins them and doing that he loses his absolute power, there’s a reason they are a company and and not a party proper, UKIP having internal democracy was a hindrance to him in the end, he learned that lesson.
