Dunno if this thread will stay up, but Storm the Castle aired about a week ago in Japan. Can't find full Japanese episodes online, but Disney Channel Japan put up a one-minute episode preview/commercial so you can hear a bit of Star-chan and Toffee-san's dubbed voices. In typical Japanese trailer style it spoils most of the plot.

-Called "Akuma Buster Star Butterfly"
-As you could probably guess, Star has a much higher voice while Marco's is a bit lower
-All characters from Mewni speak with the Kansai dialect
-Few names slightly changed. Queen Moon's name is "Moonbeam" for some reason. Ludo is apparently called "Emperor Ludo" here; though he has a castle he doesn't actually seem to be royalty in the original and his minions call him "Master." Probably other changes too.
Far as American cartoons go it seems to have a decent number of Japanese fans and cute art.
