Hi @tebetada
Thank you for your support.
It's a good idea but there should be only one source of truth i.e Either like button can push the post to the top or the upvote value. It may become really confusing if it is implemented at the blockchain level but this can be managed at the Front-end level.
It's a choice of preference and anyone can make their own product on HIVE blockchain with their own set of features.
