subtropical guilds for lychee, guava, carambola

Hello,
I live in a subtropical climate in SW Florida. I would like to establish guilds around my tropical fruit trees but have not found any specific advice online. Does anyone have experience using lychee, guava and carambola in their food forest? What are some symbiotic tropical plants? I already use Pigeon Pea shrubs for food/nitrogen but would like to integrate more diverse plants.
THANK YOU!
Maggie

I don't know the rules regarding links here, but I think this thread from a Thai based forum may hold a lot of useful information and links.
