That should work, a slow change with several smallish water changes over several days.
Corydoras panda and C. sterbai are being tank raised so if purchased in a store will most likely not be wild caught unless it is a speciality fish store that does direct importing. C. trilineatus [the usual non-julii species] I'm not sure about, but I believe these are being commercially raised. However, C. panda is a sensitive cory, and all 3 of these would be more likely to spawn in soft water. You have different temperature requirements though, so check our profiles on that.
I can give you some links to spawning tips if asked.
