If you mean a brand having an old and a new logo, this already happens. ETK has a circular (I-Series) and ovalish (800- and K-Series) logo, Bruckell's logo has a stylized (Moonhawk) and blocky (LeGran) form.
Ibishu has both "old style" black background logos (Miramar) and more stylized see-through variants (later models). The badge on the bootlid varies between pre-facelift and facelifted versions of the ETK I-Series.
