Even more puzzle ideas

A 3x3x6 cubic ( I know a fisher cube version has been made, but I do not belive there is a normal one.)

I have know idea what to call this cube. A 6x6x6 bandaged like a bandaged 5x5 ?

A puzzle where werever there is a complete line (except for the white/yellow corners), you can 'flip' the puzzle, for example:

The first one is actually a 3x3x6, which is mass produced.

It could be done, yes, but to go through the efforts for a disproportional 5x5x5 when the only legal source for a 6x6x6 offers a 5x5x5 already? Not likely.

I don't understand the third one. It looks interesting though, so maybe you could explain. The title "Flip Puzzle" makes me curious.

First, the 3x3x6 you linked to can not turn like a 3x3; this one could.
Second, the flip puzzle would be magnetic, as almost every piece is moveable. It basically turns like a trivial cross cube, with extra cuts. It could flip on any complete cut, like my scrambled picture shows. The white/yellow can also flip, but would flip the pieces around it.
