There are a couple issues with this - the first is that a blood will outgrow a small vision cage pretty quickly, so that's a lot of work to put into something that they'll only be in a short time. Second, you need to be able to take out and wash the water dish or tub. With the sometimes crazy amounts of waste these guys produce, and their lovely habit of crapping in the water dish, trying to use a filter to clean the water is pointless. Also, the naturalistic enclosures work best when they are a good size larger than the snake because of issues with waste - if not, you constantly have to swap out substrate and clean it out anyway.

You could always just try a decent in between setup with mulch or bedding and a good sized tub of water.
