Calculations for the kaon capture, electron pair, and hyperon ([ital Y]) production reactions, [ital p]([ital K][sup [minus]],[ital e][sup +][ital e[minus]])[ital Y], are made for [ital Y]=[Lambda], [Sigma][sup 0], and [Lambda](1405) using our previously developed crossing and duality constrained electroproduction model. Because there is no constraint on the minimum 4-momentum transferred by the timelike photon ([ital q][sup 2][ge]2[ital M][sub [ital e]][sup 2][similar to]0), we observe that the low-lying [rho], [omega], and [phi] vector mesons are kinematically accessible, producing up to four orders of magnitude enhancement in the theoretical hyperon production cross section. We also discuss the significance and utility of this dramatic enhancement for investigating several important topics of current interest.
