theoretically yes, but i would avoid it, as on high load the sync could
take too much time. You wrote you have a shared storage, why not using it
for sessions ? Eventually you can have a shared cache (but i ensure you
that redis became more efficient than uWSGI cache once networking is in
place)

probably i would add more sections in the ini file:
[base]
... common options ..
[node1]
... options of node 1...
[node2]
... options of node 2...
then uwsgi --ini file.ini:`hostname`
btw in 2.0.6 and 2.1 branch the if-hostname logic has been added:
[uwsgi]
if-hostname = foobar.local
socket = :4041
socket = :4042
endif =
if-hostname = foobar2.local
socket = :4043
socket = :4044
print = i am the %(_) node
endif =
in addition to this remember that the magic var %h contains the hostname
