No, he would be picking-up a basically 'bankrupt' business on the cheap, picking up the valuable transmission slots, very limited on Freeview not so much via satellite, plus the channel numbers (very limited on Sky, not so much on Freesat & Virgin) across all the platforms, there is probably some bits of infrastructure that could be used with their own studios.
He downgraded his plans for 'News UK', because of GB News launching, taking that out, changes the picture completely, let's not forget what he did with the so-called 'merger' of Sky TV & BSB back in the day, which was basically a take-over.
He's still planning to launch a 'News UK' TV service on streaming platforms, there're clear benefits to putting that on broadcast platforms for a few hours each evening. It would be run professionally and easily pick-up GBN viewers & more, he has his own sales house with well connected contacts in the advertising agencies, so wouldn't need Sky Media to sell the advertising & take commission.
