OK. If this would be the only reason to have a slightly thicker
wire to Vbatt or a capacitor and maybe a separate fuse than
its probably not worth the effort.

I'd put power drivers to separate board(s) alltogether, with
sufficient power lines of course.
But I have to admit that this schematic was for
an 'integrated ECU' not a general solution. 

Thank you David for the argument.
