Abstract Experimental measurements in pA collisions indicate no D meson suppression ($R_{\rm pPb} \sim 1$) but a surprisingly large $v_2$. To better understand these results we propose a system size scan at the LHC involving $^{16}$OO, $^{40}$ArAr, $^{129}$XeXe and $^{208}$PbPb collisions. Using Trento+ v-USPhydro+DAB-MOD to make predictions, we find that the $R_{\rm AA}$ tends towards unity when the system size is decreased, but nonetheless, in the most central collisions $v_2{2}$ is almost independent of the colliding system. These results are analyzed in light of path length and initial eccentricity variations.
