I believe I can augment your weapon using my own fearsome and dangerous PUNNING CLAN. First, you will need to check the blood type of your jedi's arm. It will, by sheer coincidence, (or perhaps your quartermaster's dilligence) be the same as your own. The next part for my clan is to remove the marrow from the arm (I'm sure they got the whole arm, so there should be some in there) and clone it. (At this point, freeze the arm in carbonite in case you need it again later.) The clan will then merrily replace your marrow with the cloned jedi marrow. (since we know that midichlorians [sic] are found in the blood, it stands to reason that they are in red blood cells and therefore marrow as well.)
Now you wait. Build up a goodly high midichlorian infused red cell count. The next step requires a retrovirus. Probably wouldn't be a bad idea to make a gate copy of yourself. Program the virus to reproduce if it finds itself in a red cell, attaching to midichlorians in the process, if it finds itself in a regular cell, deposit any midis and die. Also, the clan is to make the virus highly susceptible to say glucose levels or something, so you can kill it off if it's working too quickly or you're ready to try out your new powers.
The clan is the only weapon capable of accomplishing this feat as it stretches bad puns to the limit. (program a virus...mwa ha ha)
Hmm.. this should've been funnier. Oh well, the punning clan is probably too powerful a weapon for a newbie such as myself. Hopefully I won't destroy too many in my attempts to use it as a force for.. uh.. good..
Final step: find some weak willed jedi (such as "the chosen one") and mind-trick him into giving you his lightsaber. You can become as powerful as you want since the retrovirus increases your midichlorian count over time. Oh and if you go dark, please don't hurt me.
