D&RG Class 56/60 2-8-0 and Class 48 0-6-0t in HOn3

How can I make HOn3 models of the D&RG Class 56 and 60 Consolidateds as well as the Class 48 0-6-0t ? I know that Kemtron has produced them at some point, and that Precision Scale took up their production, but as of right now, they don't know what to do with them, as they're not producing any at the moment. What can I do instead for a cheap price that a 16 year old can afford with a job where he earns 100 per weekend? Should I just 3D print the bodies, chassis, and buy driving wheels and pony trucks from other manufacturers? I know there are companies that produce custom brass models, but I don't want to do that because it would be at least $1K. Is there any other methods I could do instead? Answers will be appreciated.
