All that time. All that grind. All that money and effort to build a battleship that can withstand anything... Yeah, I get the desire for it to be invincible, but good piloting and outfitting makes it that. It's not the ship itself, which so many Corvette and Cutter pilots want - that instant 'I win' button.
This is why I like hunting them with my friends - to remind them they are not the apex predators.
Anyway, the one's with the skills to back up the ship are really fun to behold (and fly with!). Bumping up NPC difficulty, like Fren said all those moons ago, would absolutely be a boon in every way.
Making the NPC's harder wouldn't make PvP any more appealing. It would just satisfy the need some Commanders have, for all players be measured against PvP, and it's associated builds. Turning Engineering into a requirement for everyone, right away, rather than have Engineering be a long term goal for moderate Commanders.
Let's concentrate on making PvP influential and meaningful for those that enjoy it, rather than attempting to raise PvP to dominate every players game.
