It should be OK.. I sold a couple to a family about 3 years ago and while the contour might be slightly larger than the sporter (because they came with iron sights) I doubt it will be excessive..
Just a little more freefloat and that doesn't hurt a damn thing.... If not, it is so simple to remove material from the barrel channel of a stock. There sure are a lot of guys that can't do a simple task like this that it keeps you in business. You must love those guys..
