I understand your perspective as there are different times where creative / purposive individuals generate various ideas and solutions.
First, it is instructive to note that an NGO is usually established for the advancement of any religious, educational, literary, scientific, social/cultural development, sporting and charitable cause.
This means that an NGO should have a mission or purpose.
To cater for your intention, you may make your purpose broad or select a mission or purpose that can push different ideas. E.g. An NGO for the advancement of XYZ, An NGO for the promotion of XYZ. the word "advancement" can ordinarily include various other things with the overiding effect of advancing.
Hope this answers your inquiry.
