In other words, you shouldn't have to go to the lengths you propose to get something that works for you.
Here's the thing (trying to reset the spirit of this thread)...I have something that "works for me" now. In fact, I'm pretty happy with it. Mostly I'd be doing this for fun.
But everything you read says that the rear brake doesn't really add any stopping power, so given that with my usual braking behavior the rear brake does add stopping power then switching that lever to act on the front rim should add more stopping power, right?
