...and I made the point that I've not seen that happen in any PvP game that I've ever played.
I'm pitting years of experience against your hypothetical future state.
It isn't wrong to want what you've proposed, it isn't wrong to speculate on what would get us there, it isn't wrong to post ideas.
The problem has always been that there is always a huge contingent of baying wolves that want to swoop down and destroy a caravan but there is next to no one who wants to actually be a part of the caravan. Nobody wants to be the guy in the ship loaded with goods because nobody wants to have cargo racks where they could have hull reinforcements (or whatever). You're asking sub-optimal PvP ships to enter an arena full of meta-builds (1). There is nothing attractive about that proposition to the guy loaded up with cargo - in every game I've played that lasts for about two encounters and then that guy simply either leaves or becomes one of the baying wolves.
That core problem is much larger than FDev or the problem with Power Play.
There is no point in even considering changes to Power Play (IMHO) until that nut has been cracked.

1: Until you fully comprehend what you're asking for here you're not going to understand why you're getting opposition.

This part: this already happens in PP- check out FUC, or the Kumo- it happens each week all the time by players fortifying in open.
For the rest I know exactly what you are saying, and from playing and being on the end of Powerplay I know how the patterns will change based on playing it for nearly 5 years.
With more effective opposition fortifying will change. It will be harder to do, and be less. This is good: it means large empires are harder to maintain. So, if you want to maintain your empire then you have to risk it. If not, then it becomes vulnerable. Again, good things.
In solo you can get away with a T-9 100% of the time because there is no opposition. In open you have to run smaller, faster ships or ones that actually have shields and defenses. Again, this affects fortification rates, which is good. There will not be wholesale slaughter with people crying. It simply won't happen, so stop trying to paint it that way- people will have to rely more on skill and properly think about loadouts and tactics.
So, in capitals you'll have defenders interdicting attackers while fortifiers slip through, or try to pass. If the defence is good then slower more vulnerable ships are possible. If not, then you have to use skill and decent ship builds. In essence its a game of catch, all in real time.
Money is no object any longer. VO mining in hours nets you hundreds of millions of credits. In an end game feature people are loaded with money and nothing to do with it.
What you don't understand is that Open PP is not about mass killing, its about modifying and attenuating supply lines and their regularity. Its allowing you to suddenly disrupt a power and fade away, and destabilize it in a freeform manner that generates proper emergent situations. I have not even touched on prep races, CZ battles, UM etc.
