Duplicate vanilla block while keeping its properties (custom crafting table/furnace/anvil...)

Hi, i'm making a mod for a private server, for it i want to make anvils more accessible.

My idea was to copy the basic anvil and create a new block that would have almost the exact same purpose/coding, so my question is, is there anyway i can copy a vanilla block entirely and just change after a few things? i know it's not possible to modify vanilla blocks but i hardly imagine its imposible to just copy their properties easily, i don't know enough about coding or even have the time to bother spending hours on making it from scratch is there any ways for me to just have my block work the exact same way? any addon or anything i can download to be able to do what i want?
