You could do the columns and the entry, plus the two angled walls that form the "sides" of the entry. Then maybe just do a knee wall of it all around that entire facade. Warm the color of the rest of it to work with the stone colors. Be sure you blend the color of the downspouts into the wall color.

Beautiful home! I think stone on the columns, entry, and angled walls would look terrific. A knee wall around the rest of the facade may be too much. I would experiment with different designs in Photoshop or other software before making a decision on how to proceed. Be sure to pick colors that complement your tile roof.
