<p>If your ultimate goal is to publish this idea and as you indicated in your post that a) it is a good idea and b) you are not an expert in the field. </p>

<p>In my personal opinion the simplest course of action is to engage someone who <em>is</em> an expert in the field (or at least published) and bounce the idea around with them.  </p>

<p>At that point, you'll know how good the idea is - then if you choose, publish the paper <em>with</em> them.  It will likely make your paper stronger <em>and</em> increase the likelihood it will be accepted by a top-flight journal.</p>
