Models & Animations?

In my mod, I've had the thought of fully redoing the models and animations for tools, weapons, and a few other items such as the Totem of Undying. This would add an incredeble mount of work to the already ginormous project I've been working on, on-and-off, for 2 years so far (mostly planning). However, if enough people show interest, I'm willing to put in the work. After I decide on this, I will have all the information I need to continue to the next part of my plan for this mod. Also, if you'd prefer something that I didn't mention, such as changing animations but keeping the vanilla models, I will decide based on the common  consensus of people responding to this post.
