Sure it will!

In as much as Phoenix2 is built using Fusion, sure, I don't see
why Fusion can't help here. We've seen how nifty it was for
Spirit2 to be built on Fusion too. Composing the ET nodes, for
example and doing the transforms on the composites was done
quite elegantly thanks to Fusion. Think composites, think
Fusion.
