Yes, I think the next step should potentially be going towards cultured mixes of strains of bacteria that are known good that can be injected up in a solution, because while FMT can work really well, there seem to be some dangers to it depending on the donor. Having cultured, tested mixes that could go through proper trials would potentially lower the risk quite a bit I think.
