No wonder I have been confused! The set of books I can get my hands on (not mine, but where I work) is numbered like you want them.
1- LWW
2- PC
3- VDT
4- SC
5- HHB
6- MN
7- LB
When I arrange them in the 2456317 order it doesn't make any sense. You would end up reading LWW second to last. Anyway, there is an edition that does it the way you want, it is the Collier Books, 1978 edition (good luck.) Anyway, I can't remember the order we read them is, but I think it was the 2456317 order, because I know we read LWW first. It never made much sense for me to read MN first, because the joy of a creation story is that what is being created is familiar and already exists. This is the natural order: a person is born into the world and becomes familar with it before they learn how it came to be.
Pax vobiscum,
