I'm not convinced it needs to hurt you as much, but I agree that doing something extre can make it more interesing and Badlands sounds like a cute name.
If the max total amount you could gain was 12, you could even do things like Province/Gardens, Nobles/Harem, Farmlands/Fairgounds... Pay 6 once, get 6 twice actually is not all that strong, but it would add immense flexibility in alt VP games. In the end, all it does for those is still keeping two VP cards "packed" into a single stop card, but with delay and everything.
On the other hand, 12 enables you to gain Colonies, especially if the wording isn't careful about you having to gain a first card that still leaves a second one to gain. Interestingly, this doesn't come up with a total cost of 10 as quickly, but it does. For instance by choosing a Colony after cost reduction, or when Duchies and Estates are out.
So your wording would have to do a "choose two Victory cards in the supply" first. This however still has issues. For example, can I choose the same card twice? If I can choose e.g. Duchy twice and there's only one in the supply, do I gain no second card? I already chose. This wording's going to be tricky. I actually had a lot of that trouble before when working on Assemble...
