Probe cores with built in fuel

[VektorWorlds]

My biggest problem with probe cores in KSP... is just that they look UGLY. All of those fuel tanks make it look so unrealistic and completely-not-at-all streamlined. There should be 1.25 meter (maybe some at 0.625 or at 2.5) probe cores with Monoprop built in. Not only is this realistic but I feel like it would be easy to make. The probe cores would basically look like the large probe core in the Asteroid Day pack. We don't want to need structural panels to build good looking probes. If all else fails I guess I could make this mod myself, but the textures would be worse (I only have experience with small amounts of pixel art) and there would certainly be tons of bugs and glitches

It wouldn't need to be very large, only like 5 parts at max. Maybe a monoprop engine or two just to make things easier.

You can do this with Module Manager quite easily. No new textures required.

Here you go, this will add monoprop to the Asteroid Day probe core. Just save as a file with .cfg extension in your GameData folder (for example "probewithmono.cfg")

@PART[HECS2_ProbeCore]:Final
{
RESOURCE
  {
   name = MonoPropellant
   amount = 50
   maxAmount = 50
  }
}

You'll need Module Manager installed, of course.
