Web snapshots

Given this:
Initial state (Adobe RGB, 16bit, 3072×2048, PSD)

Is it possible, with a single keystroke, to do this?

Merge visible
Convert to sRGB
Convert to 8bit
Resize to width of 994 pixels (constrain proportions)
Pause for Smart Sharpen values
Save as minimally compressed jpg

Then restore to the initial state

In other words:

Press a key
Be presented with the smart sharpen dialogue with image in the new state
Make adjustments and click ok
And end up with everything the way it was before pressing the key and a jpg snapshot

Thanks,
Ron
