I have one very interesting idea using this buran energia craft in normal KSP. while in realism the full tank will be required for getting it to orbit but in the case of normal ksp we will have quite a lot of fuel left. what if instead of filling up the core stage with fuel completely we reserve some space on the top, just enough to allow energia to take itself,buran and this space which will have cargo to orbit. This cargo will have a interplanetary transfer stage which can be attached to the buran with a docking port on the back. Say we use the interstellar engine mods then we can use the vasimr, nerva and direct cycle nuclear turbojets instead of the normal engines. the nerva will be available in the interplanetary transfer stage, nerva and nuclear turbojets will be used instead of RD 58 and a jet engine. We could maybe theoretically take this thing to mars and back.
Just a idea i wanted to share after watching far too many awesome buran energia launches on youtube.
Thank You
