I still think Paizo would make a ton of money by converting their older APs over to 5e. They don't have to switch to 5e entirely, but they're leaving money on the table by not making it easy to run their older stuff on the most popular system - and perhaps new stuff should be published in both 5e and Pathfinder formats. (I know Morrus, for one, vehemently disagrees)
But flooding the market is never a good plan. They should do 1 a year IMHO.
I think it would be very difficult for them to do, because they'd have to follow the 5e SRD (unless they sold them solely on the DMs guild, which I don't see that ever happening). So I imagine there would be A LOT of rework needed in those APs to make them compliant with the SRD. Of course, a ton of rework would be needed anyway just to convert from what is basically 3e to 5e. Probably just isn't worth it to them.
