Why welded between two plates?  Run coolant through it?

I looked a lot at making a lot of little nozzles out
of a single plate either cast or machined with
micronozzles across the plate.  Cast inconel plates
with the nozzles preformed aren't that expensive,
and can operate at the required temps for many
of the propellants.  Probably including your
mixed monoprop.  Stainless is probably even
good enough for that mixture.
