Ha ha, nice.

You can do something similar to that with awk.

The classic book titled The Unix Programming Environment, by Kernighan and Pike, has some good examples of that.

You have to quote and unquote parts of the awk command appropriately, so that some parts of the command are processed directly by awk, and others by the shell (first).
