haven't heard from anyone on this topic
This is because I don't really understand what you are trying to talk about, are you asking us if we want to startup our own masternode coin or are you asking if we want to setup a masternode because what I can see from your topic is that you are asking if we want to create our own masternode coin which doesn't even make any sense, I think you should change the name of your topic and you will definitely get people who would reply.
Which MN are you interested in?
You may choose your own coin from here
https://masternodes.online for masternode based staking but I am not seeing it as a good thing as people are heavily dumping their MN rewards rather than setting up another MN node. You may lose your capital rather than recovering it. This was the exact thing happened to me with CDM coin MN set up.
