It's an interesting point about whether Tierney and Attwell should make room for Jones and England. I think removing Tierney and Attwell is very hard on them but it does seem fairly clear that neither of them is going to have much of an international career.
Other nations seem to find talent at a very young age and nurture it into a FIFA badge at about the age of 30. However, this can backfire as was the case with Attwell's first incarnation into FIFA. I think certain influential people saw in Attwell much more potential than there actually was.
Who is there in England, already in their mid 20s, and really impressing people? I don't know their ages but the names I have heard spoken of very well are Doughty, Edwards and Donohue.
I think for me, UEFA clearly see Tierney and Attwell as VAR officials. With this now being a separate section on the list, and not exclusively for FIFA refs, it would make sense to remove their badge to allow Jones and England to step up if they see both as future international referees.
In terms of beyond that, I think the names you have mentioned are a good shout. Speedie and Barrot both got an FA Cup 3rd round tie which must be a good sign. Also Will Finnie had a decent game at the weekend in my opinion in what was a very challenging game to officiate. Maybe hes one to watch?
