Basis for a 1:25 Jet engine

[landman]

I am planning to build a 1:25 version of this puppy.

I realize there is no such thing as a 1:25 jet engine and that it'll have to be mostly scratch built. However there may be some parts that could be useable like nose cones, blade sets from some kit engines. It works out to about 96 mm in length by 32.5 mm in diameter. Any ideas on this. It was the photos of the blade sets in this thread that gave me the idea of using model parts. On the other hand, are there any aftermarket parts either 3d printed or resin cast of blade sets large enough for this?
