Have two aloe types you could try. Aloe aristata and Aloe saponaria both do well outside here in the mid atlantic. Would like to trade for A. "truncata" or any dwarf or variegated agaves.

I'd be interested in your Aloe aristata. I also noticed you have some euphorbias. I lost all of mine to the freeze this year (we don't usually freeze) and would love some cuttings if you have some to spare. I have a few other varieties of agave that have pups (the really small types - I can ID them for you) I could send along with the parryi t. pup. Feel free to contact me direct by my email.
