I dont think this will work, all Amiga-like systems are in heavy development and setting these "standards" may risk the momentum.
I also believe that at this time, we need to let the devs do their thing, implementing the things they feel is necessary for the continuation of their respective systems.
On the other hand, i do not mind standards for stuff like office documents and the like that may encourage cross platform communications, but that is something spanning over all computer systems.
