It doesn't appeal to me, but this is very subjective. I suggest you try:
See your FXT/custom height, colors, wheels
See what your FXT would look like in custom colors and different heights, with different wheels

You can play with different heights without having to do the costly mods first here. Personally I like mine not to low and not too high (too low doesn't look good to me and will detract from FXT SUV attributes; too high won't perform as well as lower will).
Cheers,

PS: Are you SURE it's just 1/2" ??? I sure looks higher than that!
