As well as BR ex-LMS style lined red, a couple of Princesses were done in red, but with "normal" passenger loco BR style orange/black/orange lining.
One was 46204, Princess Louise, and a good colour pic of her in this "interesting oddity" livery appears in the latest Steam Days, November 2004, Page 644 opposite Contents.
This would be an easy introduction to reskinning for someone if Pete's OK with it or even just for private use............no lining to change, just a re-colour with the colour replacer tools, rename and number.............
Have a try!!!!!!!!!!!!!!!
