Ended up using a Flintloque KGL figure as a Hagrid proxy - truly a giant among men.
Lord Byron came as a Barbary Corsair, Mary Godwin from Redoubt, Lady Faversham from Westwind, Geordie roadworkers (how did Auf Wiedersehen Pet get in the booklist?) from Foundry, Lieutenant Javert from Mantic, Tess of the Baskervilles from Reaper.
Rules? From the back of an envelope.
And in true old school club style, we took paints and brushes to continue painting some of the figures we were using at the table.
