DB Engine :: Defining MAX And MIN Server Memory Settings On 2 Node Cluster

On first Node A: The server has 16 GB of physical RAM. 
On second Node B: The server has 10 GB of physical RAM.

Now, this being Active Active, Node A can be clustered on failure onto Node B..Now reporting server is configured under these two nodes, with defined MAX and MIN server memory of 12 as MAX and 0 is min IN GB.Now with this setting on SQL whenever the cluster moves, such config make OS goes low on node for 10 GB.I am only left with option of switching this MAX and MIN to a default setting or is there any other alternative such as script which can change this setting accordingly when cluster moves to respective server.
