My hubby has been doing prop for some hanging baskets..maybe you can do something similar..I just do not know how heavy your statue is..if you have a more even place to put it in...I have such a small place so I have to confine any structure within the perimeter of a planter
Obviously your statue will be heavier, but you can try doing this post pedestal, using quick dry cement..or maybe reinfornce some more underneath with some pavers.
We got this really heavy water feature, but it came with the equally heavy stand. Maybe some water feature sellers may have a similar stand you can use for your statue.
