User blog:Tomj8937/Children of Achilles, will this fluff work?

Hi it's Tom, Im Curious if the fluff to a chapter I made up, works before I put it up on the site. I wont bore you with the entire story, just the main details, it follows:

The latest founding a chapter could be, 26 or 27, The Children of Achilles were truly blessed with a miracle. One of there initiates known as Memnoc of the holiest Skies, was implanted with a rather odd gene seed, said to contain part of Sanguinius' soul. after a few weeks of having the gene seed implanted, Memnoc noticed 2 tiny feathered appendices sticking out of his back. Fearing he had been Corrupted by a faulty gene seed, He Went to the apothocarium. After 2 days of studys and x-rays, the apothocarys were certain that the gene seed had caused the mutation. So Memnoc was sent to the Librarium to find out if he was tainted by chaos and kill him if necessary. They Psychicly scanned him with the most powerful psykers they had available to them. However Memnoc had no taint of chaos upon his body. Far from it, his soul seemed to shine with pure faith in the emperor.

After a month. The tiny appendages in his back and grown to full fledged mighty angel wings, allowing him to soar above the ground even in power armour. Sure enouth, as more and more time passed, Sanguinius began to manifest on the body of Memnoc. The Children of Achilles saw this as a miracle. Within 200 years Memnoc had become the Lord commander of the chapter. And has been so ever since.

I havent though about colours yet, and the name may change. For the war-cry though, I decided on: "The Primarch Lives!"

What does everybody think, please don't say it bends cannon.
