Well, first, a better naval position would allow them to have a bigger role in dictating the limit, and thus might get a better ratio for them, such as 6:5:3 for BBs, not 5:5:3 like OTL.
I just don't see it without a massive change to GB/USA, both are really happy with the 5.5 part its the 3 bit that could hurt them so more likely 6,6,3 than 6,5,3 IMO.
On a solely navel front I would prefer less rather than more!
Finish the QEs then rather than Rs stop for ASW escorts rather than R&R, LLC, Hood (and starting sisters) The RN does better in WWI due to more light escorts and maybe completing
Conte Rosso and
Giulio Cesare as CVs in time for Jutland......
from the start of WWI to WNT each navy would have built the following,
the RN has 5 QEs and the only 2 working WWI CVs (really 20Kn CVEs) and has only just thought about starting 4 G3s, and is completing a set of 4 big (Renown/Ark Royal sized) CVs with its experience from the war.
the USN has built all the standards 11 (2N,2P,3NM,2T,2C) and working on 14 (2C,6SD,6L) more and one CVE,
the IJN has built 6 (2K,2F,2I,1N) and has 7 building (1N,2T,4A) and one CV (H)
With more cash I can still see GB wanting to accepting a 5,5,3 ratio,
CVs are easy as all navy's as OTL but RN has 4 Renown/Arks and 2 Argus, this would be acceptable to all IMO
(RN is better than OTL but not very obviously, 4 better CVs for 4 conversions but number similar, maybe USN/IJN get 3rd/4th conversion?)
In battleships the RN will scream that it needs newer ships
to match the USN/IJN, and demands the 4 G3s what would be acceptable?
IJN has 10 new/useful 14"/16" ships built at a minimum, the USN/RN would need 16.6 ships (5,3)
USN has 13 or 15 of the new/useful 14"/16" ships and the RN has 5 ok/good 15" ships and up to 15 very hard worked/old 13.5" ships
Say a WNT that gives USN the 4 Colorado's in return for only having 15 or 17 with 2 12" ships (all 14"/16") ships ?, RN gets the 4 G3s and gets 17 (5QE+ 13.5") ship due to the weak old 13.5" ships ?
I will stop as wondering off topic...
