Rebirth Expansion

LOL. Charging attack is AI. I learn something new every day.

Strictly speaking, it is. The logic for deciding to charge is built into the AI for the monsters which you typically see charging. This is in contrast to certain other behaviors (most notably, following and opening doors) which are simple flags in the monster data. The latter are trivially changed, while the former is difficult to insert into a new monster (unless you just change its attack type to Charger, which takes away any specials its old attack type might have had).

(an idea though would be altering the speed of the projectile and i'm not even sure if that's possible)

Not only possible, but probably easier than most of the interesting changes. Just set the star's speed a bit higher when it is created. Watch out for wall-penetrating stars though... Now, if you want the star to change speed while it's in flight, that's not so trivial.:)
