The Royal Navy says no. End of story.
RN is much weaker ITTL. Much of there budget is being spent on large 500K to 1,000 K standing army expansion, probably stationed in Canada. USA will also invest in a navy. USA had almost no military budget OTL, so we will see most of increase come out of standard of living. UK had larger budget, so much bigger share of Army budget increase comes out of other government budgets (think Navy). Unless you write a really odd TL where both the CSA wins and the UK supports the union, the USA army alone will change the whole military structure of UK. The UK could afford a large navy only because of lack of standing army.
So lets look at Prussia to get grasp of USA army. A decade or two after war, the USA will below 40 million population or above. If we take the 1914 model for Germany to get mobilization rates (65 million or so), we get a standing army of 550K or so USA with mobilizable strength of 3,000K. The usa may not go as high as germany, but even if we cut down to a 2 million man army available within 90 days of outbreak of war,and assume 1 million go against CSA, then 1 million are free for Canada.
IF, and it is a big IF, the UK supports the CSA directly, they are in bed with the CSA. It sounds nice to say the will leave the CSA, but the USA will be out for blood and revenge. The CSA is the only realistic counterweight to the USA simply taking all of Canada as compensation.
Now this also gets me to another bug I have with TL where UK sends ground troops to ACW and the south wins. One book had 35K UK troops. The USA first response in such a war is to split Canada into pieces. We had a huge number of troops and the east west RR are not that far into Canada. All you really get is something like the in the West stands on defensive and Sherman march to see becomes Sherman taking Ontario. And yes, he would burn it down too. Unless UK intervene early (1861) before USA has large army, I am not sure its army is big enough to save CSA.
