Simply Bigger Trees SE has been created by game modding specialists, namely, Fadingsignal. The mod is intended for users who wish to enhance the size of trees in skim, at least those that do not appear in vanilla skim. It will increase the trees' sizes by about 25% on normal maps. This should, theoretically, make all trees appear much bigger than they were in the vanilla game. If you want to take this feature further, then I recommend that you create your own site tree meshes using the same format.

I have only had limited success with the Vanilla version, and it seems like these trees are more bugged than worked on in the recent versions. It's almost like they are made from a different game or are entirely unrelated. There are several crash bugs when moving the camera in the trees, and I've also experienced clipping errors when cutting down large trees. I can only see this problem becoming worse as I use same files.

I'm planning to make an addon that will allow me to move and position trees. It will be similar to the one made by Fadingsignal, but I haven't got around to making that one just yet. I will post any new updates on my blog. The team who made Simply Bigger Trees SE is working on another beta release, which should soon be available for download.
