Science landers that stow in a single Mk3 cargo bay

[fourfa]

This is a concept I've been working on for a while: a miniature, reusable science lander as part of a Grand Tour mission with an orbital mothership.  It can park in a single-length Mk3 cargo bay, and close the doors for aerobraking and transit. I'd like to see what other players come up with!  The requirements:

1) Fits entirely inside a single, closeable Mk3 cargo bay.  Orientation doesn't matter, but I find it a lot easier in flight if you can dock nose-in or tail-in, instead of crabbing in sideways.  RCS system is semi-optional, but it sure is easier to dock when you have it.

2) Enough dV and TWR to land on vacuum worlds Moho and smaller (Moho, Vall, Eeloo, Mun, Dres, Ike, Bop, Minmus, Pol, Gilly).  Landing and regaining orbit on Moho is something like 1800m/s.  More is better, enabling biome hopping too.  Bonus points if you can handle Duna as well?

3) Carry all the stock science experiments (atmospheric sampler optional)

4) More part count is worse.

5) Keep clipping to a realistic level, otherwise it's kind of a meaningless exercise.

 

Here's my current favorite, which gets 3100m/s dV in vacuum with 26 parts and (ahem) only a little clipping.  Bottom docking port and top probe core are rotated 45 degrees to match the RCS blocks, as a control-from-here point.  Otherwise RCS mounted at 45 degrees to the pod is very inefficient with monoprop.

Interesting concept, and a useful premise. I'll have to try this sometime.
