Those inflatable tubes are fairly wide and you don't have much roof to work with. most of the support would be provided by just two of the tubes. I would also be concerned about the keel compressing the tubes when shock loaded (ie: hitting bumps). An air bladder is going to momentarily compress under load and most of the compression will be right under the keel. A foam block will not compress as much. Can you carry the yak upside down?
