  A novel approach to reconstruct inclusive $\bar{B} \to X_{s}
\ell^{+}\ell^{-}$ decays is presented. The method relies on isopsin symmetry to
extrapolate the semi-inclusive signature $X_{b}\to K^{+} \ell^{+}\ell^{-} X$ to
the fully inclusive rate in $B^{+}$ and $B^{0}$ decays. We investigate the
possibility to measure branching fractions and other observables such as lepton
universality ratios and $CP$ asymmetries. As a proof of concept, fast
simulation is used to compare the $X_{b}\to K^{+} \ell^{+}\ell^{-} X$ signature
with a fully inclusive approach. Several experimental advantages are seen which
have the potential to make measurements of inclusive $\bar{B} \to X_{s}
\ell^{+}\ell^{-}$ decays tractable at a hadron collider.
