Transmission database - for all your crank / bb / bottom bracket questions

Hi, I hope this is the right place to ask this:
I have a gravel bike with MTB Sram GX 1X11 groupset that I want to turn brifters / drop bars.
I plan to mount sram rival 11s brifters.
I wonder:

• would they fit my GX rear derailler? I heard Sram won't recommend it.
  
• would they fit my TRP Spykes disc brakes?
  
  

Thanks for your help!
