The Global mm-VLBI Array (GMVA) has demonstrated the ability to resolved whatmay be the general relativistic shadow of the supermassive black hole in M87 at86 GHz, as well as delineate the inner jet to $\sim 1$~mas distance. Weinvestigate the ability of the planned ngEHT, and the ngEHT + ngVLA at 85 GHz,to image such a nuclear 'ring', and the associated jet, using a constructedmodel based on the current estimate of the ring size, and a scaled version ofthe best VLBA image of the M87 jet at 43 GHz. While the resolution does notimprove due to the limit set by the diameter of the Earth, the ngEHT aloneshould provide both a higher fidelity image of the ring on scales $\le0.1$~mas, and a good image of a more extended jet to $\sim 1$~mas. Adding thengVLA improves substantially the dynamic range (factor 3.5), as well as addsthe ability to image structures on larger scales, in this case out to at least5~mas, and potentially to much larger scales given the $\sim 10^5$ range inspatial scales covered by the ngVLA itself. Both arrays provide good imagefidelity ($\le 0.1$), in the inner $\sim 1$~mas, but the ngEHT-only image doesnot reproduce the outer jet well, or at all, with fidelity values greater thanunity. The combined array reproduces much of the outer jet with good fidelity($\le 0.3$). Adding the ngVLA also decreases the susceptibility toantenna-based phase errors by a similar factor, and improves the ability forfringe fitting and subsequent phase and amplitude self-calibration. As forscales $< 100~\mu$as, ie. the ring itself, adding the ngVLA makes little changefor very bright sources, where uniform weighting can be employed. But for faintsources, adding the ngVLA adds potentially an order-of magnitude sensitivityimprovement (Issaoun et al. 2023).
