Seems unsurprising, really. Probably not thought about much before as splicing of this type has focused on treble dodging minor, where there isn't much space in a half lead to do an awful lot.

Examples exist in minor. A surprise method with 14.56-12.36 middle section can simply swap it for 1456.12.1256.56.1236 so
Stafford Double -36-14.56-12.36-14-56 le 12
Golden Wheel -36-1456.12.1256.56.1236-14-56 le 12

That's a pretty esoteric example, perhaps it's an idea that could find more use on higher numbers (as you show) where I have no doubt many more unimagined possibilities lurk.

MBD can introduce these, though, and hopefully some answers will be forthcoming.

Fascinating. Sounds like the sort of thing there should be a rational explanation for. I'll wait to see exactly what MBD has to say.
