Going from IM sub specialty to EM?

Hi everyone, Has anybody heard of someone with an internal medicine (even subspecialty) background go into ER? First of all are there ERs that will hire board certified IM people? Is there a way to be able to take EM boards or do you have to do another residency? I have gone through IM and subspecialty training and wish I had done ER for a variety of reasons. Im not sure if at this stage of my life I could do another residency and am wondering if anyone knows if there is another way?... Going from IM sub specialty to EM?
