This note describes a unified approach to the reconstruction of the decay modes B⁰_d -> D^±_d π^∓, B⁰_s-> D^-_s π⁺, and B⁰_s-> D^±_s K^∓ within the DC06 simulation framework for LHCb. The expected signal yield after the offline selection and the first-level hardware trigger in 2 fb^-1 of data is 1.23± 0.08 . 10^6 events for B⁰_d -> D^±_d π^∓, 1.7± 0.5 . 10^5 events for B⁰_s-> D^-_s π⁺, and 1.4± 0.5 . 10^4 events for B⁰_s-> D^±_s K^∓.
