Extra Large Slipcase Covers For Dansco Albums?

I know Dansco has their standard sized, official, slipcase covers which fits their standard album sizes. For me, I think slipcases would be a good idea. The problem is, I'm too cheap to purchase 10-15 slipcases for all my albums at $10-15 bucks a pop.

I am wondering if there's any companies out there that make larger slipcovers that fit multiple albums at once. E.g. I'd love if someone made one that fit all of Dansco's US modern albums in one cover, or two US cents albums, or 3 US quarters, etc. Or even better, custom ordered at the sizes you need.

Anyone know of any 3rd party companies offering any remotely similar to what I'm describing?

Thanks.
