Well,it will be a great idea but lets face reality:Creating a cryptocurrency requires alot of very hardwork and financial support. Hardwork here means you have to put your mind and in fact your all to it which means that you have to remain focused on your objective.To be frank from my experience from crypto projects,the creator brings the idea and is kind of the leader of the community,he determines what the final goal is and how he wants to meet that goal.Meaning that sometimes,he will end up meeting unforeseen obstacles that will require using another pathway which he has figured out already.In that case,he may not need to involve the community because he has found the new way and has to follow it.That is why most projects update their roadmaps along the line.so yes,you may want to be more community-involved but sometimes it doesnt make alot of business sense to want to involve everyone when you can just go ahead with the idea you have.In any case,you can focuss on such a currency but that will mean you need to target developers who understand the technicalities and can always offer help.
