Project-Wide Cut and Paste All Effects for Da Vinci Resolve XML Roundtrip?

Recently ran into this while roundtripping from FCPX to Da Vinci Resolve and back again via XML.

While this is a fairly painless and impressive process, there are still many effects that Resolve cannot apply upon importing the XML Project/timeline from FCPX.

The goal here is to:

1) Temporarily remove - but save - ALL effects from a FCPX project/timeline.

2) Export a "clean" XML from FCPX to Resolve that has no effects, and hence results in an error free XML import into Resolve for grading.

3) Finish grade and export a project/timeline XML from Resolve to FCPX.

4) Apply ALL EFFECTS saved from step 1 to the color graded project in FCPX.

Theoretically the projects should all match each others regarding ins and outs, with the only change being the color grades applied to the clips generated by resolve.

Any ideas on how this might be accomplished? Perhaps (hopefully) I'm drastically overthinking this.

Many thanks as always.
