Ave to BRB might be alright IF your kids are old enough to self rescue. We floated from Avalanche to Thomas road (2.5 to 3 miles from Carbondale) a few weeks ago. After BRB there are some low bridges to watch out for. At 1500, you might have problems with these in a oar raft. Paddle raft meant we had to get down. The level is dropping fast, and you might not have a problem with the bridges... The A to B section is pretty mellow with some big wave trains.
Cemetary is good to go. See post on Ramp Closure in Carbondale from a few days ago. Big wave trains in cemetary proper.
Claimer: Someone that makes a claim that they have been there and done that, can do anything you can do better than you. I hate "claimers"
