If you want a recon ship and dont have the option of using the order destroyer, I would go with the zoner gunboat that's being added. It's small, lightly armed but has a lot of cargo space and hull strength - and it would fit the role much better than a juggernaut.
i m certain you would use the ship in a most responsible manner - and would still not feel fully happy with seeing anyone but a zoner flying a juggernaut. - but other than that.... i ensure you, - you do not WANT to fly a zoner juggernaut. - the barge might be the largest "ship" around, but the juggernaut is still larger than the rheinland battleship ( longer, wider and almost as high ) + i gave it a very generous hitbox, which covers a lot of space around it, too - so no one can complain.
besides - don t see a reason why the recon destroyer should not be included. - but it wouldn t be a very powerful ship - nothing that stands a chance against another capital ship of its own size or larger.
edit: the zoner gunboat has no sensors modelled and its not meant to be something of that kind. - its a VIP transport for zoners - and a high security transport for precious goods. - not meant for scouting at all.
the zoner juggernaut will have a ( supposedly ) very powerful radar installation ( the funny thing in the back ) - but its anything but unconspicous....
