I am not a developer, just a community lead.  The technical insiders have made it pretty clear they will support either a fixed block reward or a fixed rate for Aeon, but not experimental or complex emissions (in order to preserve the social contract of Aeon).  
  
Other ideas are certainly encouraged, and if you look around you can find some easy tools online to generate Cryptonote coins. From there, with the proper coding abilities, you could implement any reward mechanism you like.  
  
But it feels like since a decision needs to be made quickly, that decision must be between two simple choices: fixed blocks or fixed rate.  
  
Also, I need to do some research into Boolberry.  Do they have a trailing block reward or are they pure hard capped deflationary?  If they have a hard cap on coins, then it makes the case for low inflation in Aeon all the stronger - that way there is an original Cryptonote fork with all three economic mechanisms: deflation, disinflation, and inflation.
