Well, you pays yo' money, and you takes yo' pick. Having the 12th string raise to C# on the A pedal does make it a little stiffer, and adds to cabinet drop. But neither of those are problems I can't live with on my MSA Millennium, Zum and Emmons p/p 12-strings. I just played around with your 4/5 chord a little. It's a nice sound. But it's not something I would use enough to trade my low minor root for. It gives you a movable power chord down there on the lowest strings in minor keys - very powerful stuff for blues, rock and jazz. I live there a lot.
But this does raise the issue that, if you put changes on those lowest strings of uni, you get more cabinet drop than 10-string E9. But 10-string C6, with three low string stops on some pedals has the same problem, yet people learn to deal with it. Because I tune by ear, I tune to the cabinet drop, which is then not noticeable to me except playing at the nut. With the A and B pedals I get about 2 Hz (8 cents drop). To minimize the problem at the nut, I split the difference. So my E chord is tuned to a reference of 441 (+4 cents), and the pedals drop my A chord to a reference of 439 (-4 cents). Both of those are passably close to the rest of the band tuned to 440. If I tuned either the E chord or A chord dead on 440, as many people do, the other chord would be 2 Hz or 8 cents off at the nut, which would bother me.
The Bb change on string 5 is certainly a favorite of many country players to minor the A chord with the pedals down. There are so many other ways to get minor chords on a uni that I don't miss it. In the 6th neck mode that gives a M7. But, again, there are so many other ways to get a M7 chord, I don't miss it. The 1 3 5 of any minor chord is also a rootless M7 chord. For example, A C E is Am, but also FM7 without the root.
To be honest, I'm not a 6th neck specialist. B6 is mostly another position in E9 for me. I do play some swing style in the B6 mode (as well as rockabilly and T-Bone style jazz-blues), but I mostly approach it as a lap steel, with extensive use of my lever that lowers 8th string E to D, the equivalent of the IV9 chord on pedal 6 of C6. A lot of the things the pedals and levers are required for on C6 can be gotten other ways on a uni. The more I get used to uni as one big tuning, the less useful I find the traditional C6 pedals and levers. But like I say, I'm not a C6/B6 specialist. If I were, I'd add a center lever cluster and put Bb there.
