There are two different things that are often confused:
Based on your description, I guess you have the first kind of ticket as this is the only one where flights actually get cheaper (as this is seen as an often undesired flight connection).
If you have a combination of both you can’t use Rail&Fly to get to Frankfurt instead of Cologne as the Rail&Fly ticket has the destination “Cologne”. But thankfully for you, to get from Kassel to Cologne you need to connect through Frankfurt (where you of course can just leave).
Now for forfeiting the AIRail part (QKL–FRA leg):
Technically, you would be in violation of the conditions of carriage and the whole ticket can be cancelled. In practice this doesn’t happen as long as you consider the following (based on a lot of second-hand experience):
If you have any baggage you should leave it at the AIRRail counter in the FRA train station, not the regular check-in counter.
If the QKL-FRA train is severely delayed your flights are going to be rebooked, especially if you had a short connection. Of course this is something you don’t want in your situation. It is advisable to book a long connection in FRA so this doesn’t happen (and you don’t care for the connection time anyway). In case of delays you can tell the staff that you got to the airport in some other way. As long as this were feasible they will accommodate you (for example, if the rail line is closed on short notice there is no way you could have gotten to FRA in under 90 minutes).
The reason this works is that you can use any carriage in the QKL-FRA train but only one has Lufthansa staff in it. Deutsche Bahn staff (which works in all other carriages) should tell Lufthansa if they see your ticket but in practice this often doesn’t happen and sometimes they don’t check tickets at all. So they can’t be sure whether you have been on the train or not.
