You could make it use `kind: pip` and just remove you install-commands. 
For example, for something without dependencies, the following should
be enough:

```
kind: pip

sources:
- kind: zip
  url: pypi:p/pytz/pytz-2017.2.zip
```

Also, I defined the "pypi" alias in my project.conf:

```
aliases:
  pypi: https://files.pythonhosted.org/packages/source/
```

That makes all those urls much nicer. :)

Of course the hard part is automating the dependencies though, creating
an element for each one. :-/
