It will be interesting to see the results. Many terrestrial plants have extremely delicate root hairs, so there is the possibility that the shrimp will damage those. But then, since the roots will have adapted to aquatic conditions, maybe they won't be so fragile. Also, I'm wondering whether or not there's a possibility for the tomato to poison the shrimp. Tomatoes come from a family of plants that is well-known for the number of unusually deadly plants (like nightshade and datura) and also the same family as tobacco. So, there is that potential that they could be harmful to the shrimp.
All that being said, my guess is, as long as you don't over do the ferts and obviously don't use pesticides, I think the shrimp could do alright. Just keep the water fresh (doing frequent partial water changes).
