  We propose to raise the critical temperature $T_c$ for superconductivity in
doped C$_{60}$ molecular crystals by increasing the electronic density of
states at the Fermi level $N(E_F)$ and thus the electron-phonon coupling
constant in low-dimensional C$_{60}$ nanoarrays. We consider both electron and
hole doping and present numerical results for $N(E_F)$, which increases with
decreasing bandwidth of the partly filled $h_u$ and $t_{1u}$ derived frontier
bands with decreasing coordination number of C$_{60}$. Whereas a significant
increase of $N(E_F)$ occurs in 2D arrays of doped C$_{60}$ intercalated
in-between graphene layers, we propose that the highest $T_c$ values
approaching room temperature may occur in bundles of nanotubes filled by 1D
arrays of externally doped C$_{60}$ or La@C$_{60}$, or in diluted 3D crystals,
where quasi-1D arrangements of C$_{60}$ form percolation paths.
