Just need to scare up a pair of genuine hoods:
Toothpicks and a magnifying lens helped immensely in ensuring a clean result.
Edit: Found hoods on Ebay, and have got three pairs on the way. But, they're coming from Italy, so I'll likely have to wait until a week or two into the New Year before I can mount these, hoods included, on the Bianchi. But they sure look pretty sitting on my desk in the meantime!
