Yes, this can be easily done.
Step 1.
In epilogue of node1, use the following javascript:
uda.node1Actor = getActor(); // place the actor value in UDA called "node1Actor".
Step 2. In RoleScript of node2, use the following javascript:
var assignee = uda.node1Actor; // retrieve actor value from UDA
setActivityAssignees(assignee); // set activity assignee via javascript
Note that in step 2, you only want to set rolescript. Do not specify the role. Leave it blank and ignore the warning.
You will have to define a UDA called "node1Actor" to hold the actor value in step 1.
