If the original material can be easily identified, they might, but I don't know for sure. If it's been heavily edited so it looks nothing like the original, it shouldn't be a proble, but again, I don't really know for sure.
The best thing you can probably do is ask one of the members of Degica's staff, as they can give you a more official answer.
It'll probably also depend on whether the original material came as part of the RTP, a purchased pack, or given freely. If it's free, then I'm guessing no problem, as long as you adhere to whatever restrictions and credits are required.
If the RTP, then they probably won't care as long as you own the editor that the original RTP resource came from, as well as the editor you are using the revised version on.
But if the revision came from a purchased resource pack (like the Samurai Pack), then sharing and receiving edits is more or less against their EULA.
