Shape Mod Help

[DizzypheasantZZ]

I want to own the following shape mods: 2x2-5x5 Mirror Blocks, Mastermorphix, Axis Cube, and Ghost Cube.
I believe that I can build all of these except maybe the Axis Cube and the Ghost Cube.
Here are the ideas that I have had so far.
Mastermorphix- Make it like a Half-truncated Cube but cut more off each corner, and build it into a pyramid shape.
Ghost cube- Misalign each layer and then cut it back into a cube shape.
Mirror Blocks- build up several of the layers.
I would like some more ideas before building these puzzles.

why don't you just buy them?

If you want to own them, you can buy everything except 4x4/5x5 mirror blocks, just using mass-produced puzzles (nothing expensive and custom-made). I'm not sure how hard it is going to be to make the bigger Mirror Block puzzles - building up is relatively easy, using some thin plastic sheet, but thinning layers down will be harder because you have to make sure not to make them too thin.

Some puzzles, such as the ghost cube and the 4x4 and 5x5 mirror blocks, cost a lot more money than I would want to spend on a cube. Even the cheaper ones such as the mastermorphix I could get for cheaper if i buy a Shengshou or YJ Guanlong. Since the quality of the puzzle doesn't matter, I can also sometimes find a cheep Rubiks brand at a thrift store.
I also do it because I enjoy it. It is a lot of fun to turn a 3x3 into something else and make a new challenge.
I wasn't quite sure if I would be able to sand down a 4x4/5x5, I would just build it up. I had thought about getting a smaller 4x4/5x5 so that the finished product would not be too big.
