It is certainly possible to re-coil and/or re-wick almost all of the BCC types. Re-wicking is actually very simple (unless the old wick is so gunked in there that it won't come out without destroying the coil). Re-coiling is a bit more work, but it's still very doable.
Look for "evod coil rebuild" on you tube. This one isn't too bad:

You don't need all the pliers and stuff, I take the heads apart and put them together with fingers and fingernails. (You do need something like a tiny screwdriver or drill bit to wrap the coil on, though).
If you just need to re-wick:
a) Pop the cap off the coil head
b) carefully remove the old wick (often they come out more easily one strand at a time) with tweezers
Dry-burn the coil once all the wick is out.
c) Put in the new wick and trim it
d) Pop the top cap back on.
