Your Ultimate X-Factor Top 12?

[xDramatick]

If you could compile a Final 12 out of 3 contestants, for each category, from any series, who would you select? Also, what mentor would you give them?
Here's mine:

Boys;; Mentored by Dannii Minogue.
- Shayne Ward (Series 2)
- Austin Drage (Series 5)
- Lloyd Daniels (Series 6)

Girls;; Mentored by Cheryl Cole.
- Alexandra Burke (Series 5)
- Diana Vickers (Series 5)
- Lucie Jones (Series 6)

Overs;; Mentored by Simon Cowell.
- Maria Lawson (Series 2)
- Daniel De Bourg (Series 4)
- Ruth Lorenzo (Series 5)

Groups;; Mentored by Louis Walsh.
- Eton Road (Series 3)
- Bad Lashes (Series 5)
- Kandy Rain (Series 6)

Not necessarily the best contestants but definitely a lineup I'd like to see :]

Who would you select?
