You are confusing things: 256 bit is weak for normal RSA. But it is
very strong for a symmetric block-cipher like AES. In addition, there
is no good way to extend a block-cipher to a key-lenght longer
than it is designed to take.

On the other hand RSA or ElGamal can be done for any key-length.

You have not understood the problem or rather is absence. Sorry.
