Yup - the Radetzkys iTTL would be full dreads.
The former seems reasonable with a larger AH economy and the latter as well.
I hope Germany doesn't try to annex Bohemia, the borders would look terrible.
I think the fleet numbers are way off. Germany OTL, as of the Battle of Jutland, had 16 dreadnoughts. They're unlikely to ever reach that number without a similar investment, that didn't happen OTL. France having 27, plus maintaining a large army, is simply beyond their capacities, and likely to send Britain into a frenzy, given that as of 1916, the had about 28 of them. A-H having 11 is also probably beyond their capacity, given that at the outbreak of WW1 they had only 4. It's also worth considering the Navy was a common service, so it would need to pass funding from both Parliaments, which would be an issue ITTL.
As a worthless nitpick, Wilhelmshaven was the main North Sea port of the Kaiserliche Marine.
Remember that the CEW is starting in early 1919 and not mid-1914, so there is 4.75 more years of peacetime naval expansion. This is likely enough time for the Ersatz Monarch class to be built by AH to bring their dreadnought total to 8. TTL Germany has also had to focus more extensively on their army due to being committed to a two-front war with France and Austria (Iron Triangle) and also not having a Kaiser enamored with the navy in power since 1893, so a smaller German navy is not unexpected. France also likely has had a stronger economy TTL due to a better post Franco-Prussian war (not losing Alsace, keeping possession of Suez Canal etc.) which means being able to support a larger navy. Also, apparently France bungled their naval procurement during the 1906-1914 period regarding construction and fell behind whereas TTL we are told that they built their first dreadnought several months after the UK and have been more active in naval construction.
There’s still a lot of other factors aside from construction time. The level of investment Britain and Germany put on during the OTL arms race is unlikely to be replicated, and nobody would be able to sustain it for long. I will take a guess and say that the French number came from projecting the German shipbuilding before WW1 for 5 more years, but that doesn’t take into account that it had already slowed down by the time the war broke out. Aside from that, you also need crews for the ships and general maintenance, which are pretty expensive.
