Actually Timber, it's a very easy job to renumber/rename/re-logo most loco's. As you're 'into' using household products for modelling where possible, paint/transfers can be removed easily using "Brasso" or car products like "T-Cut", applied with a chamfered cocktail stick and gently rubbed until it disappears, but being careful not to rub into the top coat of loco paint. Pretty much any name/number/logo you can think of is available from a number of suppliers (I use "Fox Transfers" myself, but others are available), a sheet of number transfers isn't that expensive, and you can then rename/renumber a loco to one that isn't available in RTR, with plenty left over for more loco's. A coat of clear varnish to seal everything, and you're done. I accept it does require a measure of patience and 'deftness of fingers' perhaps, but if I can still do it with good results with my eyesight and 'not-so-steady' hands at nearly 72, I'm sure you'd find it easy enough.
