First of all, if you are not a "real estate professional" you might want to change your profile. This may help you receive answers that are more tailored to your situation.
Second, taking your question at face value, as a REALTOR, who adheres to a code of ethics, and as a Dept. of Real Estate Licensee, "bypassing " a listing agent is a good way to have your license suspended, be fined, or face a board of greivance hearing.
Third, why would you want to do that? It sounds as though you have your property listed and you want to "sell to the buyer's agent". So there would be ONE agent representing BOTH parties, you and the buyer. That idea assumes that it is possible for one agent to negotiate the best deal for both parties. How is that possible?
And the truth is that if you are paying the "selling side" five percent, then you are giving up your negotiating leverage for a point or two. IMHO that is not smart. In most transactions I can prove to you that I actually save my client's at least my commission by good negotiating. You need to focus on your net profit, not the commission amount. Focus on what you take to the bank.
