Bash builtins really aren't that difficult code-wise. The parameter list is a simple linked list instead of an array. But you can't build them without building bash itself.
I've been experimenting with a bash builtin which creates arbitrary anonymous pipes... The behavior's interesting. Since the shell's holding it open, it doesn't block like a named pipe when you redirect into it. If it's not full, it doesn't block even when you write to it. This is of course the definition of a buffer, but it's interesting to have it happen when you haven't created your reader yet. Some useful concurrency could happen there. There might be some communication arrangements doable with this that'd be impossible with a named pipe since the shell can't open both ends at the same time.
