Your idea actually evolved for me into another (#7?), which is simple and apparent enough to be ingenious ;) DO use the partitions, but split the "2.73Tb" drives into a roughly "2.5Tb" partition followed by a "250Gb" partition of the same size as vdevs of the original old pool. Then the new drives can replace a dozen of original small disks one by one, in a one-to-one fashion resilvering, with no worsening of the situation in regard of downtime or original/new pools' integrity tradeoffs (in fact, several untrustworthy old disks will be replaced by newer ones).
I like this idea since it allows running two complete pools on the same disks without using files. Due to using partitions, the disk write cache will be disabled unless you specifically enable it.
