By Rodrigo Campos NEW YORK, April 8 (Reuters) - U.S. stock index futures were little changed on Wednesday, with traders eyeing a $70 billion mega-deal in the energy space and ahead of minutes from the most recent meeting of the Federal Reserve's policy-setting committee. * Royal Dutch Shell said it would buy rival BG Group for $70 billion, closing the gap on market leader U.S. Exxon Mobil.
