You should start the ICO for the whole ecosystem, IMHO.
This will be an interesting proposal, and possibly more options for using the token in the future.
In the situation with 3 ICO it will be more difficult to combine 3 different tokens into the ecosystem.
I work in https://snowfox.tech and I can make you an interesting offer. If you are interested, write me a private message or an e-mail sergey.philipsky@snowfox.tech
