Default Twin scroll turbo in 6 cylinders engine setup

I'd like to set up twin turbo in my 6 cylinders engine. The problem is the 6 cylinders manifold will be divied into 2 manifolds which has 3 exhaust ports each. I have 2 identical twin scroll turbos. They are 2-port turbine inlets. So I'll have 4 exhaust inlet ports total. If I denote them as A, B, C, and D. The firing order of my engine is 1-5-3-6-2-4. What should I group the exhaust manifolds to them?

What if I group all the exhausts to only one turbo, so I can divide it to 3+3 of 2 ports of a turbo, and then feed the exhaust of first turbo to the other? Just modify it from the usual biturbo setup. Any comments?

I'd just set it up so that you run the first three cylinders into the first turbo and the second three into the second. The twin scroll design is intended for faster spool times, but that's usually not an issue on a parallel twin turbo.
