Except that Holmes, poor guy, really only functions properly in his own time and place. Take him out of Victorian London and stick him on the Liberator, and his encyclopedic knowledge of tobacco ashes has just become useless.
There was a reasonably good movie (Return of S.H?) in which Holmes is revived by Watson's grand daughter after he had cryogenically frozen himself to avoid dying from the bubonic plague. Various adventures follow, but the point is made that Holmes' powers are limited - in one scene he deduces that the murder note must have been brought from nearby as the paper had not been folded (as you would if putting it in a pocket); it turns out that he is scrutinising a fax copy.
To bring it back to B7...
Sir Arthur Conan Doyle attended a dinner with the editor of Lippincotts magazine, and Oscar Wilde was also there, and was commissioned to write The Picture of Dorian Gray. So when I wrote a B7-Sherlock Holmes crossover many years ago, I had Avon attending the dinner with Watson and narrating the events of 'Rescue' (in a veiled manner) to Wilde. Thus Wilde borrowed the story from B7 and not the other way around. To further confound matters, Avon had arrived in London in the 1890s by using a mysterious macguffin found at Xenon base - which Dorian had preset to that era in order to find out why Wilde was writing stories about him.
You will be relieved to know that this story (Previous Recursions) has been hidden in a box for about 9 years and has never been published!
