I totally get it about wanting a snake with a little more spice and fire. I've considered Blue Beauties but in the end wanted snakes that are a little more willing to engage with me, responsive to enrichment and target training, etc. while still having some spice. The Australian pythons fill that role perfectly - intelligent, active, beautiful to look at and observe, extremely responsive, available in sizes from the diminutive Antaresia to the glory of the big Costal Carpet Pythons. And they can definitely be an intense snake, yet there's an odd fundamental gentleness to them if they trust you. There's a good reason that once people keep one they tend to fall in love with them.
But I do understand having a particular passion for a specific snake. You might want to look into enclosures by Focus Cubed Habitats (they made all of my enclosures), as you can definitely select larger/taller enclosures than AP offers. AP makes good enclosures, but so does Focus. And a Blue Beauty needs height.
