Yes, but how? I got really into Semantic web stuff maybe 5-6 years ago and I thought it would have taken over by now but it seems to have withered for lack of development. You're welcome to email me with your thoughts if you prefer.

Great suggestion.

Will it be unicorn-fart powered, or are you thinking some sort of genie-based system?
