So, I'd love to help but... there's nothing to show after initial work in 2011. And I found no plans to provide any updates.

Besides, this reverse engineering work should be simpler now that Skype was bought by Microsoft. For example, Microsoft no longer encrypts/destroys the executable's import table. And it seems they dumped the anti-debugger code too.

Let's also not forget Microsoft is pushing out new variants that should lend themselves to reverse engineering (e.g. web/plugin-free [0] and Universal Windows Platform [1] apps).
