I am no big fan of Reaper Bones, as I find the lack of detail offputing, but sometimes they are useful if you're looking for cheap solutions.
I bought two packs of their Ogre Chieftain for like $3.50 each and decided to convert one of them. I might use them as "Frost Giants" for my Frostgrave campaign, which I believe call for having two of them. If not, I can use them for my far-on-the-horizon Kings of War game.
The same for a requirement for two armoured skeletons. I already had Reaper's Arrius, Undead in pewter, and bought him again in cheap Reaper bones to make two.
I hate, hate, hate, though having miniatures in identical poses, so conversion it is.
The good thing about Reaper bones is that it's soft plastic, and easy to convert as a hobby knife has no problems cutting them up.
For both the Ogre and the Skeleton, I hacked off their right arm first.
and repositioned it to a different pose than their unsullied other miniature.
The only other modification I did to the Ogre was cut off the horn on his belt (they can't be both carrying those things?) and added a helmet on.
The skeleton was a bit more work. I cut out the shield and replaced it with a very different shield deisgn and cut away the blowing-in-the-wind part of his cloak. I'll let the pewter version have that look, while the Bones version will be more simplified. I decided not to modify the leg and leave it as is, but just have a different rock for him to place his boot on.
Both now look a bit different than the original.
I'll paint them at a future date.
I find converting more satisfying than painting for some reason.
