We study the perspectives of resonant charmonium production in $\bar{p} + A$ reactions within the Multiple Scattering Monte Carlo (MSMC) approach. We calculate the production of the resonances $\Psi(2S)$ and $\Psi(3770)$ on various nuclei, their propagation and decay to dileptons and $D+ \bar{D}$ in the medium and vacuum, respectively, employing parametrizations for the $D,\bar{D}$ self energies taken from QCD sum rule studies. The elastic and inelastic interactions of the charmonia and open charm mesons in the medium are taken into account, too. It is found that the $D, \bar{D}$ invariant mass spectra from light and heavy nuclei are not sufficiently sensitive to the in-medium properties of the $\Psi(2S)$ and $\Psi(3770)$. However, a 'suppression' of low mass dileptons from the $\Psi(3770)$ might be seen experimentally as well as a small broadening of the $\Psi(2S)$ dilepton spectra.
