Well, keeping shrimps in an unfiltered wabi-kusa tank setup could work... just that you don't just put in 50 malayan shrimps at once, that will naturally overload the tank very easily.
Unfiltered tanks can only support a very small bio-load (compared to filtered tanks). For small unfiltered tanks, just a few small shrimps can already be at the limits of the tank bio-load capacity, any more and the water will foul up very quickly. You'll also have to do more frequent water changes and waste removal to keep the water clean too. Basically without a filter, you'll have to act as the manual filter.
Also note that the ADA wabi-kusa plants are usually grown out in separate emersed setups before usage, so most of the soil ammonia and nutrients are already used up by the mature plants, which makes it safer to add to a tank and then add livestock in immediately.
But if the wabi-kusa was freshly made with new ADA aquasoil and then immediately put into a tank, the soil will start to release ammonia into the water column like in a new tank setup, and that will affect any livestock that were also added in at the same time. In such cases, you should let the plants use up the ammonia and nutrients to grow, let the tank cycle and stabilize first, then add in livestock later.
