If you have a good oarsman and /or padde crew, you should be able to get where you need to be on the river without too much of a problem. Be aware that if you flip it at Skull, you're going either in the Room of Doom and may not be able to get out, or you're possibly collecting your gear after Last Chance. But, the move to get left at Skull isn't too bad because the rocks necessitating that Right-to-left move are gone.
However- the scout eddy is not a great option because it will be difficult to peel out from that spot into the part in the current where you want to be. So- Skull is almost certainly a no-look for the rafters. I may not be the best person to ask, either, because the highest I've rowed it was about 14K; I've only kayaked above that, which leaves a different impression.
I would suggest having the raft catch an eddy about 50-100 yards upstream, on the right; and have the kayakers scout the drop from teh traditional scout eddy. You might be able to give them some hand signals as to the best way to proceed.
Your vehicle of choice would be a New Wave Cruise Control
I have a June 17th launch and I just picked up a old Kendo (8'9" of longboat love)- should be a hoot.
