Printing Large Objects, Orca Profiles, Filament Pigment and MORE!!!

This Episodes Questions:

I recently purchased a Elegoo Neptune 4 Max to print large things.  It came with a 0.4mm nozzle for some reason.  My plan was to replace it with a 0.6mm or 0.8mm nozzle.  As a test I kept the 0.4mm on.  I scaled the object in Orca slicer and chose standard 0.2mm layer height.  Orca said it would take 7 days to print.  I added a second Elegoo Neptune 4 Max printer in Orca Slicer but this one with 0.6mm nozzle.  I chose standard layer height again (0.2mm).  I sliced the model and Orca said it would take 9 days.  Weird.  I selected extra draft layer height (0.28mm) and sliced it again.  Still, 9 days.  What am I missing here?  I expect a bigger nozzle and larger layers to print faster.  Is there a way to "download" updated profiles in Orca Slicer?

Crazy idea: How feasible would adding pigment to the filament during printing be? The thought occurred to me while listening to you all discussing multi material systems. If you could just load spools of white or clear filament and then change pigment while printing, imagine the possibilities!
