The issue is you put out there 'current' as in able to purchase new. At this time the only option is the H based setup with a 100mp sensor to match the frame size of film. If you wanted to deal with used gear, there are lots of options, but the sensor won't be the same size as the film exposed. The Hasselblad V setup would be fairly close, but you can't purchase a new 503cw, but the CFV II 50c or using an adapter with the V lenses on a X1D/GFX is possible. Going with a CCD back would get you closer to the film size, but the price just went up.
The Leica setup doesn't translate to the MF world. There are lots of cool MF film cameras, rangefinders included, that don't have a digital mate.
