That's one of those things that sounds like it might just work, or might just end in disaster. The launch wheels should be able to take the weight and a certain amount of jiggling about. However, it's not what they were designed for.
With the right weight distribution, it can be fairly easy to move a boat a reasonable distance on two wheels. Alternatively, what about adapting a folding launch trolley and fitting a detachable nose wheel?
