It'll be considered. There's war plans for all kinds of stuff people don't think about when that kind of money is involved. Doesn't mean it will happen. To several of your other points..
The AFCS just dropped QB's in? Like Mariota being the second pick or Watson being traded up for in the middle of the first round or even Bortles at three? Those are all cornerstone moves. That those teams have been in perpetual rebuild or not built enough mode for 15 years is it's own fascinating slice of sports history, but I think you mistake the Jags, Titans and Texans as Super Bowl contenders. They're not. The Colts with a healthy Luck and a reinforced Defense and some help on the O line are (which is what we're hoping is going on-I do think we see things trending towards that).
Luck is in fact a very unique talent. I don't think Rosen or Darnold are. In fact I'd bet the house this QB class is getting way too much hype. As I said elsewhere I don't think there's more than Rodgers who's a more talented guy at the position than Luck, so you'll have to forgive me if I simply don't think there's equal value out there.
To the point of "why can't you trade him when injured". Well you (the team) can/could, but again- what's equal value? Is equal value dumping the contract (that doesn't really work in the NFL) or is it a Pick (not having any idea if said player can actually play) or is it Aarron Rodgers and his dissimilar yet similar status.. Can't play.
And to this idea that the franchise (GRIGSON!) "botched his career". Nothing personal, I know this is how we as sports fans state things, but that's a crap take in many ways. Injuries are not something that's determined by anything other than simply playing the game. Grigson did a excrement job of designing the team to win, but that's not why Luck got hurt. It's simply not apples to apples. Go look at the plays he got wrecked. Running around outside of the pocket (which aren't sack's that the o line gave up).
I hate this Colin Cowherd-esq logic. Can't stand it.
Oh and failed miserably. When was the last time another AFCS team made it to the deflategate.. err AFCCG? Thing's haven't been perfect, but it's not "fail miserably" territory. It's underachieving and mismanagement- which sucks too..
