lol, your suggestion is to send a key through asymmetric encryption (which must be definition be as long as the plain text). Then you send an encrypted message.

lol, your suggestion is to send a key through asymmetric encryption (which must be definition be as long as the plain text). Then you send an encrypted message. If someone eavesdropped on your key (send through asymmetric encryption) the message is compromised. You might as well send the complete message through asymmetric encryption then. You just wasted bytes and gained nothing in security. The problem with the one time pad is that it opens up a myriad of side channel attacks on the key.
