Not sure why you would even need a 2-part lander. I built a large lander that, once put into orbit by the assent stage, could fly to minimus, land, take of again and fly back with 10 per cent of the tank left.
Your design could probably be modified to work, but I think you should simplify it to 4 small nuclear engines on fl-t800 tanks around a x32 and x16 tank, with a lightweight pod/micro lander/probe on top. Not a very powerful design, but safe and lag free transport for small landers and probes. It can reach orbit over Duna and Eve and return and do one way trips to any of Jools moons. Hope I helped
