Is there a Morphing for histograms (not PDF)?

Dear ROOT experts,
I was looking at your RooMomentMorph and RooIntegralMorph classes of RooFit. I also looked at your documentation about the interpolation between multi-dimensional histograms using a new non-linear moment morphing method: http://arxiv.org/pdf/1410.7388.pdf
I want to use these morphing methods for my proper analysis. I have histograms template as an input, which represent my signal shape, normalized to the number of expected events. The problem is that these histograms can have negative bins and cannot be converted into RooHistPdf, and so unfortunately I can't use the RooMomentMorph class.
Do you know some tools that can do the morphing as RooMomentMorph but on histograms? If so, can these tools do the interpolation with multiple morphing parameters?
Thanks a lot for your precious help!
