I have updated Balloon Head, Noa and Slippy's Viewmodel Mod to support BLT 2.0.
However, updating weapons to be affected by Viewmodel Tweak is beyond me.
Extract to mods folder.

Unfortunately, as of the release of SuperBLT this mod is now outdated and needs yet another unofficial update to work! If you, the viewer of this post knows how to update mods to support SuperBLT and wants to take a crack at reviving this, do feel free to DM me (Renatus) :)
