That wouldn't be a bad idea as I have seen many coins switch over to ERC20 tokens and it has been a great success and for the ones that are worried about staking, ERC20 tokens can be staked and its much easier. Also it can open up the doors for the dev with future developments so I think it can be a good idea if the community is up for the change.
ERC20 isn't a bad idea, but I guess we should determine the type of products / service we would like to pursue below making those types of decisions. Maybe the underlying functionality of Ethereum wouldn't work for the project. I'm not against the idea, we just need to pick a platform that would work for what we want to achieve.
