I, personally, dislike addons that come from other games, they never look good. The only good addons are those made originally and made to fit Blockland, instead of transcribed from another game in an attempt for it to fit into Blockland
I would agree, however, that T+T is rather boring nowadays, because its so old and we are used to it being the only good pack used. A new pack in the same style but with a new approach may be called for inorder to make for a more positive gaming experience.
