I've not tried it and I'm always surprised when people mix larger species with shrimp as even small tetra can wipe them out but i'd imagine that it would be hard to mix the two. Adults might be alright but smaller ones would be a tempting meal. The normal advice is make sure it is heavily planted so that some may survive.
Getting enough light to the base of your tank might be a challenge for carpeting plants. I tried Monte Carlo with low light levels and the little growth I had was upwards rather than spread out. Others with more experience might be able to give you some better tips though.
I settled for increasing the amount of leaf litter instead. This tea stained the water for a while but I grew to like the “blackwater” effect and miss it now that it has faded. So will probably start adding new leaves every so often again. This also reduced the pH slightly but not by much.
Your tank is really developing well by the way, good job!
Nice scape. I would also consider the differing water parameters bee shrimp and the rainbows prefer. Rainbows are happiest in harder alkaline water whereas bees prefer soft water. You might be better off with cherry shrimp, or rili shrimp if you want the stripes. These might breed faster for you and give a better chance of the project working.
I had some blue shrimp in with bosmani rainbows and they disappeared very quickly, presumably eaten. Amanos were fine.
