Wanting to know, best way to convert the Tri-ang Princess Victoria to Canadian Pacific 1215

[Max's Model Railway]

Hello, I've wanted to talk about this for some time, I just never really got around to it. 

 

I have been wanting to convert a Tri-ang Princess Victoria into Canadian Pacific 1215, I've been wanting to use the cowcatcher off my official one as the model doesn't have a chassis...

I've ordered a 8P 4-6-2 for use with the project, and I want to add a headlight and a flickering firebox, I was hoping to use the locomotive with the American styled Matchbox cars from

days gone by when I'd run trains, it would be a big help, the Canadian Pacific I own is in poor condition and I'd like to reuse some of it for something more common / conventional 

 

Thanks again!
