here is the process for the the connected variants to the Uncanny X-Force, Vol. 1 # 19, Wolverine and the X-Men, Vol. 1 # 01, X-Men: Legacy, Vol. 1 # 259, and X-Factor, Vol. 1 # 230 were for the ‘X-Men: Regenesis’ storyline, which covered the new status quo of the various X-Men books after the ‘X-Men: Schism’ storyline.
The line art for the variants is by Nick Bradshaw, and I believe that Justin Ponsor is the colorist.
