The `as` should be avoided at all costs. It's only something you desperately use when you need hacks. Like:
```python
try:
    # fast!
    import simlejson as json
except ImportError:
    # built in :(
    import json
```

I recommend you import the whole modules. Like:

```
import crashstats.crashstats.models
import crashstats.supersearch.models
MODELS_MODULES = (
    crashstats.crashstats.models,
    crashstats.supersearch.models
)
```
