These look good, I especially like the Gypsey's charm as this is what the 1E bard did.
I am toying with the idea of implementing a 1E bard, but its not very high up on my list of things to do.
The charming you propose does not (IMO) scale faster enough against the enemies you meet, altough you may not want the bard singing all the time. I have been persauded that unless a bard sings, they are a poorer version of the FMT. Also a sucessfull resistance to a charm lasts the whole encounter.
I'd consider decreasing the saving throws faster, say -1 / 8 levels, or offer the charm as an inante earned before L20, with reduced saving throws.
I suggest some of these classes should also get degraded theiving/sneaking skills.
