I can't speak for why HTTP::request and HTTP::method are read-only commands, but the overhead of doing this at layer 4 should be minimal if you filter the payload appropriately. You know that the TCP::payload of a GET request will start with;

GET /some-uri HTTP/1.

so simply issue a TCP::release if it's not what you're looking for.

By the way, if you're doing this with an HTTPS VIP, just change TCP:: to SSL:: and use the CLIENTSSL_HANDSHAKE and CLIENTSSL_DATA events.
