Are you doing this and still getting failed prints? Could be overcomplicating.
No failed prints? You’re doing it just right!

I follow a similar pattern – except I load my stls into Prusa slicer, rotate (for best quality or just-leaning-back-from-vertical, depending on how I’m feeling) and add supports. Manually inspected for possible islands/unsupported overhangs. Export the entire plate (inc supports) as stl.

Bring all my supported stls into Chitubox. Slice. Load the file into UV Tools.
Check for islands and either remove or connect to supports, manually.
Sometimes I’ll even add in some extra pixels where there’s a connecting point that looks a bit thin – but sometimes if I can see the layer(s) above are growing “too quickly” (so the tiny connecting part below might not be thick enough to support a large area).

When I get zero islands in UVTools, I drop the file on the printer and hit go.
In four years, I can count my failures on one hand.
