IMHO, that seems like a bad idea. Two thoughts (these are only very overly generalized opinions, biology is a little bit complicated):
1) You might not get them all, and the ones that survive might transfer the traits of antibiotic survival and pathogenic-ability (if present) to the new population.
2) You would need to ensure that your hyper-specific diet contains the right mixture of microbes, say, you would need to avoid irradiated food, and a bunch of other things. "Bad microbes" coming into an empty gut seems to me like a bad thing.
Thanks, both are good points! I assumed there were downsides to if you weren't able to wipe out the robust bad microbes but that's even worse than I had expected. Perhaps I'll wait on self-experimentation. The possibility of nefarious and now genetically enhanced microbes reigning supreme in my body is not cool.
