If you feel like a major project, consider that HMS Tiger shared the Colony class hull. There are two kits of Tiger; one in 1/600 from Airfix and one originally from Frog in 1/415 that was also released by UPC, Red Star and probably a few others - maybe including Eastern Express or Novo.
In the late 60s/ early 70s, there were frequent articles in Airfix magazine about converting Airfix kits to other ships. and the conversion to a Colony was one of them. I built HMS Jamaica from that article back then. Since then I've squirrled away a bunch of Matchbox Tiger kits with the intention of doing that same conversion again, but haven't gotten around to it.
The really unique triple turrets were one difficulty. For a while, White Ensign sold the turrets from their Sheffield kit, and now I think one or more of the 3D Printing designers produce them.
in short, no plastic kit, but possibilities exist.
