This one is basicly the same as yours, albeit with higher tech, but I tried to install similar components as you have. The main difference is, I am using military engines. This lowers the mass to 25.000t, which, in turn, allows me to keep Engineering spaces down at 20 (for support of the survey squadron, I put two Maintenance Storage Bays in)
I put in a resolution 1 active, so the AMMS can lock on to something and two more engines, in order to use the military jumpdrive to full capacity.
The main drawback is the jump engine, which requires 25.000 point to research - outch!!!
I then tried to optimize the design. Up the passives, but cut back on the actives (the shuttles are the eyes and anouncing the presense of the carrier is not a good idea anyway), settle for less speed (this one is sitting on a jumppoint/in deep space most of the time anyway) and drop the AMMs.

I left some magazin space in, so this ship can fulfill a secondary role as a carrier, supporting some FACs or missile fighters.
While this design lacks some capabilities of the first one, the main bonus is the jumpdrive, which will "only" cost 12.250 researchpoints.
I belive, your example shows, that military vessles (i.e. ships that need engineering to keep them from falling apart) are not realy feasible above, say, 25 to 30k tons.
6.000t ship with 3% of mass as engineering space --> 70% failure rate
9.000t ship with 4.5% of mass as engineering space --> 81% failure rate
12.000t ship with 5.5% of mass as enigneering space --> 88% failure rate
14.850t ship with 6.5% of mass as engineering space --> 88% failure rate
