Sounds great if you can do this as a longer-term refactoring task! I discussed this also a bit with Philipp on irc, and he said there's possible a need to support non-contig buffers in mtk. If that can't be done using cma helpers (usually you have an iommu in such a case, which again gives you a contig buffer in device-address space, and that can be used by cma I think), then I think it would still be useful if you use the cma helpers for the contig buffers. But then wrap them in some mtk code to switch between the two.
