Ditto with the above. A large chunk of the fun, flavor, feel, and balance, of Shadowrun comes from the integration of magic, and the timeline is enormously affected by magic, as is the very geo-political situation in The Sixth World. Playing a campaign with low magic or running a team without a mage is one thing...but trying to remove magic as the integral part of the setting (and mechanic) that it is?
Just play CP:2020, instead. It'll be a whole, whole, lot less work.
