Likeaboss,
The very first thing you should take into consideration, is your personal life.
Have you a wife, partner, children etc, will you want to live in at the pub, or have a manager, to oversee the daily running?
It is not the best environment, for a family living over, or in a pub.
If you followed in all your suggestions above, and of what people want in a pub, you wouldn't last 6 months.
I had my first pub when I was 27 yrs old, up until I was 54, so I know a little about running pubs, and big ones too, with restaurants, and bar snacks.
When you were describing the pub of your dreams, and some of our friends on here, were giving their choices, It brought back great memory's of what pubs used to be.
Those days have gone forever, so I would either go for a loud, busy, music bar/pub/club, with a manager & doormen, in the centre of a town, and stay at home with the family.
Then go in the morning/afternoon, and do your checks.
Or a different kind of business altogether.
