Impregnating a tree stump for burning out?

I've got an old cherry tree stump which I really want rid of. It's probably about 10" high by 15" across, and the problem is that it's in an awkward position at the foot of a banked area, and surrounded by paving stones, so would be very disruptive and difficult to dig out. It's inaccessible to a tree stump grinder (other than maybe something hand- held). Burning it out seems the way forward, and I've tried several times (over years), burying the thing in burning coal. Trouble is the stump doesn't really burn much as such; it just chars over, and has got quite dished on top, but there's a lot more to go. Anyway, it occurred to me that maybe I could try again this summer but first impregnate the remaining timber over a period of time (maybe honeycombing it with a drill first) to encourage it to burn properly. Anyone tried this? What would be good to use, that wouldn't just evaporate off? I'm not after getting the whole thing out - if I just get the stump below ground level and cover it with a plant tub or something, that would be fine! Or any other constructive ideas!? Probably no need to wait until summer. Possibly try a more serious fire instead of just heaping coals? If you build a temporary wall around it using old bricks, blocks and stuff you turn it into a fire pit. Then light a fire around the stump and keep feeding it for a few hours. Once you get a really high temperature the stump should begin to char away - but it will take time because the charcoal protects the wood underneath. Keep poking the stump with an iron bar or similar to break off the charcoal and this will both feed the fire and expose more wood. It may take several attempts, but if you persevere say over a couple of weeks you should be able to burn the stump down below ground level. Then again, one good steady fire could shift it.
