Sure. Provide it as a TIFF with alpha channel mask (f.e. a circular
mask) and move it to zenith or nadir by manually setting pitch value.
Output as a PSD (or PSB) with layers, enable the layer and flatten in
photoshop. You can use the same layer in multiple panoramas by dragging
it to another document in photoshop.

Of course you have to stitch first with PTGui.
