Checked in L&S demixing [27] that there is no simplification from objective with two norms to objective with nuclear norm. There's only nuclear norm in the convex approximation to the NP-hard problem.
Continue checking the others.
See also gsp_bss #22 "combined norm penalty and best individual norm".
Finish filling in references and context about the norm simplification to enable the theoretical analysis.
