if your cog and hub are both the same material (aluminum or steel) you could probably weld them together somehow.
however, using an 8t cog is a pretty bad idea. a low number of engaged teeth / severe curve of the chain will reduce drivetrain efficiency, and the cog will also wear much faster with the stress concentrated on such a small cog. then once you've quickly worn out your welded-on cog, you'll have a bit of trouble replacing it.
