The original design of the Collider Detector at Fermilab (CDF) was optimized for high p{sub T} physics measurements associated with W and Z boson, top quark, and QCD jet production. This choice resulted in an emphasis on the central pseudorapidity region ({vert_bar}{eta}{vert_bar} < 1.0) for detector coverage. Thus, CDF has excellent tracking, good calorimetry, and a suitable muon system in the central region. Even with this limited coverage, the large {bar p}p {yields} bX cross section of nearly 100 {mu}barns for {vert_bar}{eta}{vert_bar} < 1.0 has allowed the CDF experiment to make many B physics measurements. In addition, with the successful operation of the CDF silicon vertex detector (SVX), the capability for making time-dependent B{sub s} mixing measurements becomes a reality. Upgrade plans, which include extending the tracking and lepton identification into the forward region and the implementation of a high-rate DAQ system, make a time-dependent B{sub s} mixing measurement an attractive goal during the anticipated high-luminosity Main Injector collider runs. We discuss here the feasibility and potential of making a B{sub s} mixing measurement based on extrapolations of the current CDF detector performance using colliding beam data and the expected upgrade plans.
