Thanks for the comments, guys.
...it seems a major undertaking.
Either you didn't read my post very carefully or I wasn't clear enough about it
I'm not remaking RoN assets, I'm only trying to hone my pixeling skills. I guess you may call it fan art.
Anyway, I don't actually think that RoN needs a visual reboot. Current graphics are good enough to make great games with and as you said, there's a lot of them. For me, one of the main points of RoN has always been its simplicity, basically anyone can join in and add or modify the resources. My style, on the other hand, might be a bit too complex for complete beginners.
