I do all of my removals for free. Better that than the bees be killed. In my area, people do not have the money to pay for removals. Most are living from paycheck to paycheck and unemployment is high. Many times they will offer a small donation for gas, which I will accept, but I don't ask for it. I enjoy the work and I figure it saves me from buying a package. These bees have been my best producers, far greater than the packages I've used over the years. Not all gain is measured monetarily.
As for your plan, it sounds like a good one. It could help new beeks expand their apiaries, plus add a little diversity to their gene pools. I work with a couple of other beeks in my area, swapping queens raised from our removed colonies for the purpose of genetics. It has been a great success so far.
