Good point about using hybrid techniques. It probably would result in less overall quality loss. I'm not excited about calibrating my printer to print digital negatives though.
If you intend your final output to be traditional silver prints, I'd probably not bother with scanning and making a digital neg to print from. I think the process of making an interneg in the darkroom would be easier. I've read up on making digital negs because it looks like a cool way to make repeatable silver prints from images that need a lot of dodging and burning (you do all that in photoshop and the digital neg will have all that set in it), but the process of getting an inkjet to produce a negative with the correct tonality looks very hard. If I were you I would only consider doing scanning if you want to make digital final prints, or if the slides are damaged and need work to remove scratches or embedded dust.
