Users can pay fees or a portion of fees out of band to miner(s); this
is undetectable to the network.

It's also behavior that miners have engaged in since at least 2011 (in
two forms;  treating transactions that paid them directly via outputs
as having that much more in fees;  and taking contracts for fast
processing for identified transactions (e.g. address matching or via
an API) e.g. "I'll pay you x at the end of the month for each of my
transactions you process, you can poll this API". I'm aware of at
least two companies having had this arrangement with miners).

I think what you suggested then just further rewards this behavior as
it allows bypassing your controls.-- I suspect generally any scheme
the looks at the fee values has this property.
