Instead of working with Borel-equivariant functions, just work with formal linear combinations of subspaces. You will still get a representation of $U_q sl_2$. Of course it won't have dimension $2^n$. What representation do you get this way? | |

Feel free to edit appropriately. Also: Exercise: work sheafily! | |
