Can I replace the 36 and 24T chainrings on the 08 Truvativ Stylo AM crankset with a 32/22T combo?

Is the new (2008) Stylo stiffer/more durable than an 07 LX crankset? The crankarms look a little spindly for an "All Mountain" crank. Just trying to figure out if migrating my LX to the XC bike and putting the Stylo on the AM bike is worth the time and effort. I think the LX is plenty stiff btw.

Thanks!
