Every rooster is different. Some can handle being handled, some cannot. My experiences with bantam roosters and frequent handling is limited, I raised 5 in a similar manner in the past. Picking them up and petting them. One became severely aggressive and was culled. One attempted to dominate me by flogging and I was able to turn him around. 3 were fine. So the odds are good, but you may still have problems. Time will tell.
