Interesting question
I read through your posting history (just to make sure you were not crazy) and see that you do have a head on your shoulders. I hope this paragraph heads of readers who would make that assumption.
I did not determine if you have a background in chemistry or not. Trying to find the chemical components of the powder you have might be a good idea, if only to rule out solvents that might produce violent reactions upon mixing. You wouldn't want a facefull of toxic or caustic fumes. Full face shield and good gloves should go without saying.
All the cautions aside, what do you hope to gain for all this effort? Curiosity? Independence from components manufacturers? Better accuracy? If you use up all your powder in determining how to do this and succeed in your quest, can you get more?
You might try to find a copy of
The Chemistry of Powder & Explosives by Tenny L. Davis.
Many smokeless powders are based on an ether-alcohol colloid of nitrocellulose (source: Wikipedia), so I might try ether as a solvent to make your paste, but test to see if you have changed the chemical properties of your powder when you get done with it.
I suspect you will get a lot of criticism for toying with this idea, but I will not disparage you for thinking about it. But without knowing anything else about your goals and experience, my first conclusion is that you suffer from one of two maladies. You have entirely too much time on your hands or you have entirely too much of this powder on your hands.
Either way, I wish you good fortune.
I have read that there is a way black powder shooters can make their own percussion caps from aluminum beverage cans and caps from toy guns. I am not sure if that gives you any other ideas, but I though it might pique your interest, so use the information if it does.
