Out of curiosity, did you consider dumping MSDP but keeping SSM?

No, not even for a second.

What's your problem with MSDP? I mean, yes, I know the problems of MSDP, but in our experience there are more often issues with some switch silently dropping multicast packets due to some esoteric bug/limitation, rather than with MSDP. At the current, limited scale of inter-domain multicast, what operational issues have you seen with MSDP in the last few years?

Btw, maybe you had heard of the Eumetcast project coordinated by Geant; it had to do with distributing meteo data over ipv4 SSM (rather than, say, satellite) but also an ASM-dependent beacon was established in that context:

In complicated interdomain topologies it can be troublesome getting the MSDP and the BGP routing topology to be congruent, especially when there are multiple interdomain paths to consider.  It's fragile and needs more care and feeding than it's worth.
