I doubt this is possible from Your Own end. If you really need the project to be active, you need to support the project too(not necessarily financially). Most or all of these currencies failed probably because their originators were out if ideas on how to keep them alive and active. In my erc20 wallet, I have a lot of them. My friends too.... They have it them in a large quantity. It's either you help resurrect/rebuild the platform that owns the cryptocurrency or use them as a decoration to your wallet
