OP here again. After messing with the Deluxe Phaser some more, I still like it. Set at 10 to 12 stages, it gets close to the middle settings on the Phase 100. Around 14-16 stages it gets deeper like the most extreme setting on the Phase 100.
Here's what I have:
Rate 0.3Hz | Depth 3.0 | Offset 4.0 | Feedback 25% | Wave: Sine | Mix 50% | Stages 10 | Spread 10 | Level -1.5dB
Again, this does not sound exactly like a Phase 100, but it's in the ballpark. I also found a setting more like the Retro-Sonic, which is 4 stages like a Phase 90. I'm not really all that picky. I just like a fat phaser sound that retains the low end.
For the record, I rather like the Boss PH-3 too on its 10-stage setting. Not quite enough low end for bass, but it's a great phaser. Another unsung hero is the old TC Electronic TC XII. I had one in my guitar rig back in the '80s and got lots of swooshy mileage out of it.
