Oh, this is just gorgeous! Head-canon accepted!

I've decided that Susan has probably read some Emily and Leo too (either through Barbara or through guilting One into reading some to her pre-Chestertons).

I agree with the above commenter - these books need to exist. (I don't suppose we could tempt you to create more extracts...?) Amazing work!

PS: Laughed at 'At Last, The Miniskirt'. :D
