I took my T53 Mosaic and carefully warped it to match features up with the PIA11149 Feb 2009 Titan Global map.
Here is a blink animation with the PIA11149 and an overlay (not a blend!) with the T53 Mosaic.

This came out pretty good - I'm really happy with this.
Even subtle contrast differences and features seen in the Feb 2009 Map are also observed in the T53 Mosaic.
I've indicated diagnostic features that I used for the coordination:
Blue arrows indicate dark albedo features
Light blue arrows indicate darkish gray albedo features (funky graben thingy in NW)
Red arrow indicates bright blobby "island" in darker region
Yellow arrow indicates bright albedo pattern in light gray region. (near vertical bright albedo feature)
Note how the vertical bright albedo feature at west (mountains?/fracture?/other?) is present in both image sets.
