Hi Eric,
On October 02nd we released a new generation of Web Apps that are much closer to the Mobile model. You can read all about Reactive Web Apps on our forum post.
With the introduction of Reactive Web Apps, you can now convert Mobile modules to Reactive, being able to reuse as much as you wish from the original module.

Feel free to experiment with the new version and let us know if there's something we can improve.
Thanks again for sharing your idea!
Cheers!
