Help designing smaller, more compact banana circle for backyard

I’m new to gardening and permaculture. I’ve been a lurker on YouTube permaculture channels and that’s about it. I don’t know if this is even a possibility. It’s been a fun thought experiment, but I want to look further into it.

Banana circles seem to take up a lot of surface area. I don’t have that much room in my yard. I want to optimize my limited area by designing Banana Circle Lite™ while still leaving room for my garden to expand in the future.

Use dwarf banana plants. Reduce the diameter of the circle. Any larger companion plants would be dwarf varieties as well. Reduce the number of plants a typical circle might have. I live in North Florida, Zone 9a, bordering 8b. We get a couple freezes a year so, I want to use Rajapuri banana plants because they seem cold-resistant, produce fruit quickly, and are a dwarf variety.

I’m just curious about people’s thoughts on this. Any advice? Improvement ideas?
