From Private Client to Corporate Tax

I currently work at a small regional firm in private client services tax – currently about 50% high net worth individuals and 50% split between their business entities and trust/estate/gift tax returns.  I have been in this field for about 7 years now, and while I enjoy the work, I am getting burnt out with the hours demanded.  I would love to make the transition out of public accounting, but I realize this is difficult with my background.  Does anyone have experience making the jump to Corporate Tax when so much of your background is private clients?
