It doesn't seem very possible in the current structure. Nowadays, every project is working with its main net work and the dream of building the Blockchain network. Even Binance is working for that. They want to create a blockchain network which belongs completely them.
That's indeed and it looks a dream, whole of crypto already pegged with a coin that called bitcoin. Even they try to create hundreds of blockchain and if there was no demand and what they can do with it? nothing for sure.
