Storyline Select, Do we skip the skills too?

Pretty much no one has asked this question and I really want to know, Like if I get to 320+ can I go to g10 and get the beast skills or The alchemy skills of g9? Can someone atleast try this?

If you're talking about what I think you're talking about: Skipping to G10 will not give you pre-G10 skills such as Life Drain from G9. But you're still able to complete the other gens simultaneously with G10, and doing so will still give you those skills.
