We demonstrate the feasibility of realistic shell-model Monte Carlo (SMMC) calculations spanning multiple major shells, using a realistic interaction whose bad saturation and shell properties have been corrected by a newly developed general prescription. Particular attention is paid to the approximate restoration of translational invariance. The model space consists of the full $\mathrm{sd}-\mathrm{pf}$ shells. We include in the study some well-known $T=0\mathrm{}$ nuclei and several unstable neutron-rich ones around $N=20,28\mathrm{}$. The results indicate that SMMC calculations can reproduce binding energies, $B\left(E2\mathrm{}\right)\mathrm{}$ transitions, and other observables with an interaction that is practically parameter free. Some interesting insight is gained into the nature of deep correlations. The validity of previous studies is confirmed.
