I suppose he could be trained to use a lightsaber in theory...but I just don't see it.
Why do jedi need the force to hold a lightsaber? I'm sure that HK could hold one and slash at people. Actually, he should be able to use normal melee weapons too. I don't know why droids aren't allowed to have melee weapons either.
So if anyone, I would have HK as a lightsaber weilder, to make him useful.
