My first attempt at unfolding R = 0.2 and R = 0.5 spectra yielded some very spiky distributions:

This might be due to the binning I was using, so one thing I tried was unfolding the R = 0.2 distribution using 1 GeV bins and then rebinning the unfolded distribution.  Below I compare the 1 GeV bin distribution, the rebinned 1 GeV distribution, and an unfolded distribution using large variable bins.

As you can see, it kinda helps but not a lot...
