Thanks! I'm glad you like it!
About the Leslie, no, sorry, you can't use it out of the B-5 instrument. That being said, the B-5 Leslie is based on UVI's Rotary: https://www.uvi.net/rotary.html
There are just a few differences, the biggest one is the impulse responses are ours on the B-5 and they used different ones in the plugin.
