It's very unlikely that any major new features will be available by April 1st.

I like Logos' APIs (go REST!), but I'd echo the others - if the APIs are online-only at this point, I don't see a lot of advantage to using them; BibleGateway.net provides online access to many translations. Adding support for the API could be a fun exercise to demonstrate how easy it is to add a new text source, but the difficulty would be showing nice status when downloading data from the server.
