Well let's see some pics!
The Revell is the only 1/12 F40 I know of, but I've never seen it built so I couldn't identify one. I have the 1/16 Fujimi and it seems just huge- I can barely imagine 1/12.
Of course it can be superdetailed- it only depends on your references and ambitions.
I haven't seen the Scale Details sets in person, and I'm not terribly impressed with the pics they have on their site. It looks to me that the 1/12 set is the same as the 1/16 set, just scaled up. While this may seem logical, I doubt the metal thicknes also is increased- and it seems this would be a serious limitation. In 1/24 (in my opinion) PE parts often are too thin, and look like nothing more than they are- etched metal. In 1/16, this is of course that much worse, and in 1/12 I have a hard time imagining that much of anything would look right in PE. But then, I seem to be inherently suspicious of PE sets. If you need an emblem for the engine lid, get one of the Crazy Modeler self adhesive sets. The large size should fit fine, and the F40 doesn't need any other scripts.
I say strip it, take it apart, and superdetail it! Even if the base kit isn't great, it should be a fine base for a detail project.
