Neither of your expectations has any bearing on the outcome of the
calculation. Just because you did not understand how such calculations
could be done does not mean they are impossible. Your suspicion is
unfounded unless you actually verify it. Pointing out superficial
difficulties is not sufficient.

I strongly recommend starting this calculation and I offer to clarify
whatever steps cause problems. It will be up to you, however, to relate
to compare with your own work.

The logic of discussion also indicates that results of the standard
theory stay unchallenged as well. Which is fine for most physicists.
Which in turn indicates that your work remains unnoticed.
