Sorry but if you want LFQW you already have tons and tons of d20 stuff including Pathfinder 1.
What Paizo needs to understand are a bunch of things:
#1 they need to choose between being independent, small and obscure on one hand, and piggy-backing on D&D (and being hugely successful) on the other
#2 the majority of today's gamers came to the hobby with 5E. They won't stand for the kludgey mess of yore - unbalanced spellcasting, out-of-control wizards, and the other things that 5E
actually fixed for the first time in D&Ds history
The free space for Paizo remains the same as back when 3.5 started to sag: as purveyor of a "fixed" edition.
The sooner Paizo understands that if they just want to do yet-another-fantasy game, they will be reduced to the same low low level of sales as... pretty much
every publisher that isnt WotC.
The obvious alternative would be to publish a sort-of compatible:ish "advanced" 5E D&D game as their Pathfinder 2, which removes a lot of the restrictions WotC placed on themselves.
A game that would be recognizable as Dungeons & Dragons game (just like Pathfinder) but actually adds value to the hordes of 5E gamers, without devolving back into the kind of crap 5E has already fixed once and for all.
What does 5E lack?
# Player-side options. That is more detailed build choices, and using +1 and +2 bonuses instead of just advantage. Lots of 5E gamers miss the time when each level-up meant a myriad of intricate choices

# Challenge (meaning that of course any DM worth her salt can TPK her party, but I'm talking about recalibrated default settings to something less carebear)
# Monster complexity - high level monsters especially
# Proper support for the solo boss fight (a whole party vs only one single alone solitary unaccompanied big monster) that remains interesting, fun and difficult
# Magic item economy. Now that WotC is going the opposite route with Xanathar "treasure points" which essentially remove gold pieces from the game, there is real opportunity for a big trusted publisher like Paizo to build a proper magic item creation and pricing framework (building on the d20/PF experience).
That's my top 5 anyway.
