Nice set up you have here - sorry I can't offer any suggestions. You can't separate flash and camera so without other lighting I'm a bit stuck.

Close ups with camera against the glass is all I can think of.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
