Question re possible Alternator Charging rates?

It depends on the batteries, but I think you'd normally be unlikely to see much more than 60-70A charge rate. AGM batteries however will accept higher charge rates.
Your 10 sq mm cable is undersized; you'd be better using 25 sq mm. You obviously need a bigger fuse than 50A; if you use 25 sq mm cable you might use a 150A fuse.
With an Adverc regulator, you run a risk of applying too high a voltage to the Red Flash AGM battery. You may wish to risk that, or perhaps try to reduce the charge voltage to the Red Flash by putting a diode in the charge lead.
I'd wire the alternator output direct to the domestic batteries, then let the VSR connect the start battery once the house batteries have had some charge.
