I suggested doing this to GOSH in 1998 - an exact facsimile reprint of the Boy Castaways, to be released as a fund-raiser in August 2001 = the centenary. Trouble was, GOSH aren't allowed to publish stuff themselves, being a charity.
I could virtually make one myself, having 5^ x 4" copy negatives of the entire book, which is now out of copyright btw. If anyone wants to have a go, let me know and I'll loan you the negs!
