The Caribbean HRP wasn't really an HRP, it just had the neccessary UnDEFs, a skybox or two, a sand texture, and some other textures that were already in the HRP. No one really did much work for it, plus it'll be hardest because of
every enemy being changed, although slightly (With the exceptions of the Ep. 1-2 bosses and the Atomic enemies), plus new hud and pickup weapon and item sprites, with the fact that Duke himself was changed.
