Can I level concrete footings?

Uneven concrete footings for a deck - can they be leveled somehow or do I need to re-dig?

I poured a couple of concrete footings (8- and 10-inch diameter) for an outdoor deck, that go about 4 feet deep. I did the work in a rush and now I am regretting it!
The tops of the footings (where the wood posts will sit) are not level (and I mean really not level) and it seems I am left with a couple of options (other than redigging)
1 - Cut the tops of the wood 4 x 4s at an angle so that while the posts itself are not plumb, the tops of the posts will be level to allow the beams to rest on them properly.
I don't like this idea so much because the posts itself will not be plumb, and I assume this will affect their ability to support the deck.
2- Somehow, level the tops of the concrete footings - I guess I can either:
- "Cover" the current footings with wider tubes (i.e. 12 inch diameter) and then fill those with concrete and ensure that these are level - I don't know if this is a good idea because these wider forms would just be sitting on the ground and would not be deep underground like the original forms
- "Stack" the current footings with a narrower tube (i.e. 6 inch diameter) and then fill those with concrete and ensure that these are level - In this case will the new wet concrete properly stick to the dry concrete?
- "Stack" the current footings with a tube of the same width and then fill those with concrete and ensure that these are level - In this case will the new wet concrete properly stick to the dry concrete?
Do you think that any of these options are feasabile? Are there any other fixes that you would suggest or should I just bite the bullet and re-dig?
I thought about self-leveling compound, but I read that this is for indoor use only, so I guess this is not an option...
Thanks for your help!
