I haven't seen any, but I hope someone does soon because I get asked about it almost every day.
@lomo covered this pretty well already, running the controls at 4-5-0 is about as close as you'll get, but you'll never completely get around the mid scoop. Interestingly the EQ on Elementary and Dr. Wattson is exactly the same, but the last stage of Elementary comes after the EQ, so it does a little more shaping afterward that makes it sound and feel a little different.
On a semi-related note I finally got the revised boards in for Detective and have been doing some testing, and man that red channel is a winner. Both channels are great and I love the flexibility of having both, but when that red channel kicked in it gave me some feelings.
I'm still waiting on the new batch of enclosures, but I hope to have Detective available for ordering in the next week or two. Dreamcatcher needed a couple more tweaks, but what is hopefully the final revision of the board will be here for testing in about a week.
As noted above either one will work and it's going to come down to preference. My personal taste is that I like the way Elementary drives a little better than Underground Accelerator. Elementary has a hotter first stage so it feels a little more aggressive and bitey, whereas Underground Accelerator is a little more smooth. That being said it can also depend on what I'm playing. When I play my passive jazz bass I like the way it feels with the Underground Accelerator, but when I play my active Ibanez SR I think the bite of the Elementary lends itself better to a nice modern grind.
So short answer, you should probably get both just to be safe.
