[R-sig-Geo] sp and latticeExtra: add colorbar for layer drawn 'under'

I have drawn on the following posting to draw a raster 'under' a set of polygons as shown in the image link below.  The data used is available at the third link (about 650KB).

Posting: http://stackoverflow.com/questions/27062768/how-to-plot-additional-raster-with-spplot

Image: https://dl.dropboxusercontent.com/u/8433654/sp-over-plot.png

Example data: https://dl.dropboxusercontent.com/u/8433654/example.RData

Here is a brief description of each variable plotted.

R is a single layer RasterStack of sea surface temperatures
qa is a SpatialPolygonsDataFrame of fisheries management polygons
spdfbb is also a SpatialPolygonsDataFrame that contains a single polygon (created from the extent of qa)

   colorkey = FALSE,
   sp.layout = list(b = list('sp.polygons', qa, col = 'grey', first = FALSE))) + 
   latticeExtra::as.layer(spplot(R), under = TRUE)

Is it possible add a colorbar for the raster, R, as it might appear if I called...
