Is it possible to change node level settings at runtime? Specifically I'm looking to change node.data, node.master, and node.river.

No, this isn't possible. Changing those settings requires a restart of that
node.

How hard would it be to change this? Correct me if I'm wrong, but logically it shouldn't be a problem to change those settings at runtime as long as reallocation of shards or rivers (respectively) isn't currently happening. Is that fair?

Its actually quite tricky, since it might require a re-election of master
(relocation of data is simpler). Why would you need it thought? Those
settings would sound quite "static", as in if one goes with X masters and N
data nodes, one would probably keep on adding more data nodes.
