In this contribution we show start-to-end simulations assessing the feasibility of driving Free Electron Laser (FEL) sources with wavelength below 1 nm by plasma boosted, externally injected electron beams of different energies, in the framework of the EuPRAXIA project. A 30-40 pC, sub micron normalized emittance, electron bunch is extracted from a photo-cathode, accelerated up to 500 MeV and longitudinally compressed down to few tens of fs by innovative techniques, mixing velocity bunching and ballistic bunching, in order to be injected in a laser driven plasma wave. There, its energy is brought to 1 GeV (and up) by preserving, as much as possible, its good quality and high peak current. Insertion and matching into plasma is accomplished by either standard, high performances, beam optics or by plasma sensing effects. At plasma exit, a similar strategy is employed as well as for matching into an undulator. We present details of simulations, focusing on laser plasma stage, and experimental setups employing different plasma target, assess working point stability and show FEL performances for a few selected cases.
