HMS Hawkins as 9.2 inch cruiser

[tigercat]

HMS Hawkins is rearmed with 9.2 inch guns saved from scrapped WW1 monitors

The 9.2 mounting seems to weigh 45 tons opposed to 45.975 for the 7.5 inch mount so if my figures are right weight shouldn't be the problem  it'll be down to ammo stowage and internal rearrangements etc.
