Feebly interacting particles are a commonly considered extension to the Standard Model of Particle Physics. In many theoretical frameworks these particles can explain observed physical phenomena which are at tension with the current model. Beam dump facilities are a natural experimental setup for direct searches of Feebly Interacting Particles. The high intensities and low expected backgrounds provide great parameter reach for searches of decays back into standard model particles. ALPINIST is a simplified Montecarlo framework aimed at evaluating past and future experiments for their sensitivities to different models of Axion Like Particles. We present the extension of this framework to accommodate new classes of Feebly Interacting Particles with emphasis on Heavy Neutral Leptons. This extension is especially well motivated, solving multiple of the standing issues with the Standard Model at the same time. The fundamental importance of inputs on the resulting parameter sensitivity, and thus the need for a unified simulation setup, is highlighted.
