Just spent the last hour studying the Helix and also the Fractal 2 XL. It seems either of these units could take complete control of a dual amp stereo rig with ease. With my current setup being a TC Electronic G Force ran through the FX loop of each of my 2 heads, and my GCX switcher as the "brain" that splits my instrument signal and loops to add my clean boost (TS9) and control the loop on my VH4. Either the Helix or Fractal 2 XL could eliminate both rack pieces for me, add a TON more tonal options with the amp modelers, better FX quality, and simpler routing. Only catch is I have to be able to go bone dry ( guitar -> boost ->y split-> front end of both amps). I am able to do that now with the GCX and being able to turn the loops off on the amps eliminating my G Force from the chain.
The Helix worked for me replacing my GCX, rack wah, G-Major 2, rack tuner, and midi ABC switcher thanks to the 4 loops and the TRS switching for the SP77.

The Helix has 4 FX loops, the Fractal has 1. My initial thought is guitar -> Helix or Fractal -> TS9 in FX loop of either unit -> L & R outputs to front end of Herbert/VH4.
If I can go strait through either of these units dry, while turning on #1 loop (boost) into front end of amps I would eliminate needing the amps FX loops and cabling. Then when going wet obviously just turn on wanted FX accordingly and the amp models could be used through the clean channels.
I'm not sure if it can all be done with the Fractal but with the Helix and the 4 loops and main outs I'm pretty sure it's all doable. You'd essentially be running in double 4 cable method into each head if I'm wrapping my head around things correctly. Loop 1 would be TS9, loop 2 input and FX send of VH4, loop 3 input and FX send of Herbert, left 1/4" out VH4 FX return, right 1/4" out Herbert FX return. Then you can place the TS9 before the preamps of the VH4 and Herbert along with modeled pedals like a phase 90 for example and put delays post VH4 and Herbert preamps. You can then also bypass the Herbert and VH4 preamps and sub in modeled preamps from the Helix feeding direct into the power sections of the Herbert and VH4 bypassing their preamps with and without your TS9 before those modeled preamps if you wanted and delays and whatnot after them. You can also just run guitar > TS9 > herbert + VH4 dry left and right. I think you could also run guitar >TS9 > Herbert or VH4 preamp only out to both power sections so you end up with essentially a double Herbert or double VH4. The Helix has two separate DSP paths, the two lines on the screen, so you can link them together to form one long chain or you can use them independently and have the top line doing things for only the Herbert and bottom only VH4 and this is all reconfigurable based on the preset, with no physical rewiring needed, just on screen re-routing. It can get a bit complex trying to wrap your head around it since there are several ways to do things but I'm pretty sure the way I mentioned wiring it would do everything you want and more. The only tricky part will be possible ground loops since we're talking two heads in four cable method, this is true for any 4CM rig really and certainly not Helix specific. It may be no problem with zero hum or it may cause some hum and need some isolation transformers, but unfortunately that's impossible to predict from amp to amp and configuration to configuration. It can basically do anything you ask it for with the only tricky part being figuring out the best way to get it to do what you want.
