Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     16,151 lbs / 7,326 Kg = 38.3 x 9.4 " / 240 mm shells or 2.7 torpedoes
   Stability (Unstable if below 1.00): 1.10
   Metacentric height 3.2 ft / 1.0 m
   Roll period: 15.4 seconds
   Steadiness   - As gun platform (Average = 50 %): 71 %
         - Recoil effect (Restricted arc if above 1.00): 0.53
   Seaboat quality  (Average = 1.00): 1.41

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.599
   Length to Beam Ratio: 6.00 : 1
   'Natural speed' for length: 19.84 kts
   Power going to wave formation at top speed: 53 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   Bow angle (Positive = bow angles forward): 0.00 degrees
   Stern overhang: -4.10 ft / -1.25 m
   Freeboard (% = measuring location as a percentage of overall length):

      - Stern:      16.40 ft / 5.00 m
      - Average freeboard:   16.40 ft / 5.00 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 61.4 %
      - Above water (accommodation/working, high = better): 117.5 %
   Waterplane Area: 18,877 Square feet or 1,754 Square metres
   Displacement factor (Displacement / loading): 104 %
   Structure weight / hull surface area: 113 lbs/sq ft or 551 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.91

   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is adequate
   Ship has slow, easy roll, a good, steady gun platform
   Good seaboat, rides out heavy weather easily

Not sure I care for it. I thought you were trying to modernize your fleet, remove the older, slower ships. That just brings you back to your problem. Best to build 1 16,000 ton ship with 25-26 knot speed, and with 8 guns.

[The Rock Doctor]

Tis neither fish nor fowl.  I'd prefer one of your panzerkreuzers from the other thread for the role over this design.

[Jefgte]

IMO,
You could reduce protection for 12" shell & increase the speed to work with BBs in coastal operation.

A kind of ship like this one but with more protection but smaller guns ;)

I agree with the others, while it would dominate any of the Bharat or Mughal ships would it really be useful anyplace else?  I would suggest instead building a cruiser with the same gun size, 240mm, but normal armor and speed. 

Or putting an older battleship there instead.

But I doubt that would fit on 9,000t.

Or putting an older battleship there instead.

I don't have anymore to send there. One in Dar-es-Salaam, one in Hai Phong, one in Mombasa. That covers all 3 PDNs. Plus Hyäne, a semi-CDS in Vögeldreck. Now I need something to cover Sarawak,  Goa, Paderborn-Delbrock, and Aden so I don't have to send REAL ships there.

Could coast defense batteries allied with controlled detonation mine fields be a better option in some or all of those places?

There is one truism of coast defense: you can't sink a gun on land...

The man makes a good point.
