Yes, you are right, but like you said it also depends on the amount of money at stake. Also if a witness does purposely generate a certain block id, they would have to add some "random" data to the block that might be noticeable if scrutinized. Also you could limit the block used to one produced by a top 20 witness vs a backup witness, as top witnesses (like yourself!) are even further incentivized not to do things like this.
Also if you have some time I would be interested to discuss some of the "decent methods" you mentioned. In any case, thank you for the response!
This can be largely if not entirely avoided. For example, the block producer can make changes to the block that are plausible to happen by accident, for example, simply omitting one or two transactions, changing the order, etc.
I may make a survey post about it when I have time.
