Hmmm, my SAGA experience so far with skills is mostly positive.
Beefs are:
granularity is not so good. You have either untrained, trained +5, and then skill focus +5 more... Maybe skill focus gives choice of +5, or two skills at +3 or three +2 or something else.. Or remove single +5 bonus as an option if front loading is problematic
There are fewer more general skills, which is good IMHO, but there are still some mostly dead ones - climb, jump and friends spring to mind. They could be combined opening up room for perform, craft, etc. I mean really swim or use force? Even remotely comparible? I say no.
Your amount of skills is class based, okay so far. Bu titi si also front loaded and then not much... You can spend feats to adjust that, but it is pretty expensive way to go. You can multi-class and a level of noble fixes a lot, but still.. Possibly either make it 2 more skills per feat, or allow some more learned skills based on char level, 1 per 5 or something.
Anyway, if I did 4e based on SAGA I would make those changes, or something like them.
