[HoE] Wierd West Vets. [shane]

[J23junior@aol.com]

 I was just going over the Veteran of the Wierd West edge for HOE and I
noticed it said that the Vet. couldn't be something like a syker since they
didn't exist in the Wierd West.  Can this be ignored if a character has a
specific reason why he/she may have a "new" arcane background? I.E.
   -an old harrowed who joined the army in the last war and was given some
heavy cyborg tech 
   -an alchemist who developed a youth elixer and after losing his manitou
muse became a junker 
   -a hero that crossed the stone path to the future a few months ago, only to
step into a nasty rad storm and later become a doomsayer

  Do these examples seem reasonable exceptions to the rules?
