Hey, I quite like all that too!
I'd still prefer your version to have Vader say "Yes, I have felt it", and his other line start with "How is that possible?" though. ;)
Can't believe I missed Adywan's confirmed 2nd Emperor "Yes", but I've added it now. :)
I added another alternative into my post above, but I'm pretty sure we'll be hearing something akin to Adywan's trailer at the end of the day, which works just fine.
