I didn't look at the G-class, and missed it on the DN.
What are you envisioning for "improved acquisition equipment" that takes 5t or 20t? I'm thinking enclosed platform with really big binoculars...and 4 enclosed platforms...
And I am curious why you chose to put 5t there, instead of 6t into some rangefinders and a small plotting table. 

Was surprised to see you scrapping until I looked. I start Parthia's TBs with Series II under the presumption the 1890 ones were already scrapped.
Did they beat the drum slowly,
Did they play the fife lowly,
Did they sound the death march, as they lowered you down,
Did the band play the last post and chorus,
Did the pipes play the flowers of the forest

Ya know, it would help if I did the math. Must stop posting past 10pm. Would if be ok if I tweak the design to have proper FC?

So I made a mistake because its been a while and made the G-Class to .5 composite rather than .5 cross sectional. Returned the engines to 28,000 SHP and altered the freeboard a little. Revised sim below.
