No, because the TLSA record is for the CA, not for the server
certificate.  I have TLSA records for each CA I have certs for, and then
the relevant anchor names have CNAMEs pointing to the relevant CA

I will be changing from "2 0 0" to something smaller, to avoid packet
size issues, at some point in the future; this is why I've made sure
that the trust anchor cert is included in the cert chain sent inside
TLS as part of the handshake.  Viktor Dukhovni has a relevant Draft out
on operational concerns which explains this well.  In fact, it looks
like it's been renamed and taken on as an IETF WG product:
