I am tinkering with a BR standard 9F reworked into an oil-fired cab forward 2-10-2. Possibly to be fitted with twin Giesl type preheaters and a US style twelve axle Vanderbilt tender. (Supporting theory is that BR realised that throwing away these newly constructed locos was a crime, but they had to fit in with a water-troughless mainly diesel or electric worked BR, so maximum efficiency and tender water capacity is key.) The upside to this is that class 37's are thereby rendered unnecessary, with the consequnet long term reduction in pain within UK railway modelling.
