I think the key point is not whether the wheels etc are being stressed, it is to what regulations and in what context you are operating. If you are operating to public transport standards using a FLM Cat A procedure, you are effectively entering a grey area by carrying out a running take off, as you have just reinvented the wheel (no pun meant!) The FLM describes the profile used, associated with the take off and rejected take off distances obtained from the graphs, but you are not following it. If you are at the correct WAT weight you will also gain no weight advantage by choosing to do a running take off instead, either.
On the other hand, if you are operating to Cat B, do what you like! Similarly in the military.
