There is also a welcome return for Scarlets full back Mared Evans who missed last season due to injury.
"We've chosen the squad on form at both club and regional level," explained Edwards. "It might be considered that we are gambling with two or three of them but all those who have been selected are picked on merit because of their form, attitude and commitment," he added.
Jones and Norkett are just 17 while Wilkins is only a year older but Edwards has no qualms about throwing them in at the deep end.
"It's all about giving some of the promising players experience at the top level. As an example Robyn is the most promising player in her age group and she can play at either 10 or 12 so that gives us extra options. We want to put her in a big game environment during the Six Nations as we also look ahead to the World Cup as well."
The recently completed Women's Regional Championship has also unearthed some hidden gems according to Edwards.
"We didn't even know Ffion Bowen three weeks ago but she has proved in a relatively short space of time she can finish - and finish well on the wing. She is a young and exciting prospect and a player we hope to nurture through the Six Nations."
