I think fundamentally I disagree with your optimism. I've seen a number of these come and go over the decades. I do not think making something that looks like Windows would be sufficient to be successful.

No, making Linux run reliably on random laptops is already a monumental challenge.
Agreed but there have been some real strides in innovation recently in linux, definitely worth checking out :)
Regarding successful, well they already are, ZorinOS is an OS which looks like windows 7 or has some similarities to it and its sort of recommended to beginners but usually linux mate is the most recommended distro

Not sure about this but I ran linux in 15 year old dell mini like its no big deal so I can only assume that support has been better but I feel like I can assure you that linux support is really good for most laptops in my observation.
