You guys are making this too complicated - there are a variety of 700c disc forks available in carbon, at a range of prices. Most of them are intended for cross bikes, which means they will have a slightly longer axle to crown length. I can't tell what the axle-to-crown measurement is on the stock SCR 1 fork, but it is probably 370-375mm or so. Most cross 700c forks will be in the 395mm range. Cross forks will tend to have a very similar rake, ~45mm.
This will have the effect of raising the front of the bike by 3/4" or so, which will slacken the headtube and seat angle. This will require a slight fit adjustment, and will change the bike handling slightly, but whether it is an improvement or not is a matter of opinion - certainly many people like a slightly more slack angle, especially if they are planning on longer rides or commuting (as a dynohub suggests).
My recommendation, once you are sure that your steerer is a 1 1/8" steerer (rather than the possibility of a 1 1/8" to 1 1/2" tapered steerer, though the pictures make that seem unlikely), would be this Carver:

Make sure you buy a compression plug for another $20 - you can't use star nuts with carbon steerers. You can go fancier if you want, Enve and Whisky have good options as well, though you are getting into the $400+ range.
