you can derive a version of the cc-by work, eveb with no modifications. You just need to give it a different name and credit the original author. Then you can change the license to a compatible one. I suggest cc by sa since this adds GPL compatible copyleft. Changes on your version need to be relicened as ccbysa then while the original ccby version stays untouched.

This is a general principle: a work which is as freely licensed as cc by, public domain or compatible can be relicensed as-is with a more strict one.
