If you don't want to be part of the bodies that currently exist to represent you then you will need to go ahead and form your own. if you can gain enough members to be taken as representative then you will be able to interact with the regulator directly.
However it seems to me that both AOPA and PPL/IR are working towards your needs so perhaps by joining either or both of them and putting your comments forward your voice will be heard.
