There is little chance given any likely congressional configuration that a new AWB will be passed. Thus, panic posts aren't needed.
Nor do we need to re-open the UN treaty panic. Don't.
If one understands the legislative process, you don't propose counter-legislation. You simply don't pass the ones you don't like. If an AWB was passed and signed - who is going to pass counter legislation?
As far as public opinion, one notes that the public has been moving steadily against gun control measures. Terrible rampages have moved the usual folks to talk about AWBs and the like but no stampede was seen in Congress with enough Republicans and Democrats to get one through. The issue is brought up (just as the GOP brings up its extreme issues for campaigns regarding social issues), but then nothing happens. The forces that could guarantee an AWB (as happened before) don't exist outside of their choir.
