Here's what I do if I'm MK:
Sign Sessions and start Barnes over MWP. Improves our PG play, makes us a more balanced team, better perimeter defense, twin towers get regular - more efficient touches with a true PG, Kobe handles the ball less which will preserve him.
Blake runs the second unit. We are 11-5 with Blake and 6-7 without him. I'd run a 2nd unit of Blake, Glock, Murphy (for 3pt spacing ala Bonner

) with a combination of Bynum or Gasol in at all times.
Not a perfect team, but solid and an absolute tough out.
