English Banditry

Of all the linguistic ideas and flights of fantasy I've had in my life (quite a few), and all the ones I've initially hoped might be unique (quite a few), I realized I have happened across an article or reference to every single one with but only one exception. Is there nobody who is into the idea of highly customizing his or her idiolect in an explicit manner? Sure, we generally all construct our own idiolects tiny choice by tiny choice on a day by day basis as we grow up — but given the extremely personal nature of the way we speak, why doesn't anyone want to sit down and literally explicitly plan it out and choose a consistent word scheme and accent? Is the desire to do so really that different from the desire most of us here have to learn other languages and learn to express ourselves fully in those languages? To be honest, I was terribly disappointed that my web searches on the topic yielded no “custom-idiolect construction kit” or similar site where I could get a better grasp of how, exactly, to customize my English speech and what sorts of conceivable innovations I might have overlooked. (As well as how to go about systematically adjusting my speech to achieve whatever I decide is my ideal sound and flavor.)
