11-32 to a 11-36 w/ 34-50t CR

I am upping gears on a Specialized Ruby from a 11-32 sram pg-1050 to a 11-36 pg-1050, and has a 34/50t powerglide CR (5 bolt 110 bcd). I had to put a sram gx 10 sp derailleur to allow the bigger cassette range. Now the new chain is sized correctly, but is too slack in small small and ready to rip out the derailleur in big big. B screw has been adjusted in all positions to no avail. Obviously i wouldnt run in those gears but if shifted on accident i wouldnt want to ruin the drivetrain or bike. Looking deeper, the 50t is only rated for max 34t cassette cog but i cannot find a 11-34 sram cassette! Ugh. So gunna try a FSA N10/N11 46t chainring to replace the 50. Will that work? Anyone have experience with this setup? Would i need to change front derailleur too? 🙏🏼
