Are you still looking for suggestions on where to put the photorp launchers? If so, i would suggest you consider the forward launchers could go in the small space you have on the secondary hull directly underneath the impulse engines. One on either side would do nicely, I think. For technical accuracy's sake, the firing arc would be limited because of the primary hull, but it would look keen. You have enough secondary hull space that you could mount 1, possibly 2 side by side aft launchers on the dorsal side of the secondary hull, perhaps set back just a smidge from the rear shuttlebay doors.
Something else to think about....since I'm sure that carriers in Picard's day are still bomb magnets, I would suggest adding a group of phaser strips on the secondary hull, to keep with the thinking that this type of vessel would be a high value target. Don't forget the ventral side as well.
There's my 2 cents. Hope it helps.
