While a 150 can be an adequate IFR training platform, it makes a crummy IFR cross country machine due to the lack of range and consequent alternate limitations. Just flying cross country for recreation is fine in a 150 but due to its limitations, not a good choice for serious cross countries on a tight schedule. You'd be better off with a Piper 180 like Jeff's or the 182 for your mission. Just my opinion.
