Of course, some of the gear is exchangeable, depending on your needs. Make sure to hit the important Fcr/Fhr breakpoints (note that lightning fcr breakpoints are not the same as the normal casting breakpoints).

Magefist/Trang's wouldn't be needed if the FCR on Spirit is high enough. Griffon's+ Arach's, +Echuta's together have 85. The Spirit would only need 32 FCR to hit the 117 BP. You could use Bloodfists for FHR/Life or Frostburn's for the huge Mana boost instead.
The breakpoint for Lightning/Chain Lightning is 194, but 200 will give you the last breakpoint for Teleport and all other spells you might be using. --- Life is unforgiving when you make a mistake - it doesn't have a Save & Load feature
