You mean getInstanceMemento() I assume. Yes, that should work just fine.

Pruning a tree is a bitch, let me tell you. I've yet to come up with a
solution that only requires a single walk of the tree.
Do a walk of the tree, maintaining a list of nodeIDs (pageID or something)
that grows and shrinks as you walk. When you find your node (the current
page), abort the walk.

That works Justin. I have paired arguments in script syntax all over the
place. Just remove the quotes if those are NOT literal values and you're
set.

Hard and fast rule about writing recusive functions and methods: you ALWAYS
have to have a conditional (usually an if statement) based on the function
