You can get pretty much the effect you want in practice by just delaying the server greeting and/or the EHLO or HELO reply for long enough. (Much less than the standard timeout.) Subdividing the reply and putting a delay between the packets might help - you'd be detecting something similar to a common bug in crappy web servers that require requests to arrive in a single packet. However you don't need an extension to do it because it doesn't affect correct clients and there's enough leeway in the existing spec. Also, specifying an extension is a waste of time since it'll be obsolete when the bad guys fix their code.
