I'm not going to add any Blockland models that are directly based on TF2, sorry.
However, I can put various Blockland add-ons into TF2 if they're famous enough.
The idea is not to put blockland looking tf2 items into tf2, it's to put blockland items into tf2. I think that kaje's sniper rifle would be cool to put in.
If the stock sniper had a c_model, I would've done this in the first place. However, since Valve just
had to use separate arm models for the stock weapons, decompiling them results in a model with broken, hard-to-fix animations and a lot more work than necessary. I'll try to figure it out one day.
