The only problem I see with that plan is #2. That clinic is now on the hook for maintaining patient records for 7 years for patients that may not want to visit the clinic or may even move away. Now they have to expend labor doling out records for patients who just say "see ya" and don't utilize their services. For the clinic that's wasted labor.
It could work; however, if the clinic agrees to take on the records in the hopes that enough patients will swing their way to make it all worth their while (in other words, accept the risk) or if they charge a modest fee for patient record maintenance.
