If you can connect two extra disks, you can make a concatenated mirror. =
If you can do that without a reboot you can do the whole procedure =

With existing disks d1,d2 and new disks d3 at least as big as d1, d4 at =
least as big as d2:

zpool attach <pool> d1 d3
zpool attach <pool> d2 d4

Otherwise I think you are in for some downtime.
