Do you think it would not be okay to give it a try? Right now my discus are very "brave" e.g. they are always out and greeting us and "dancing" whenever we're in view. They eat very well. If I did a trial and found that their habits changed, presumably I could relocate the angels at that time, right? (Assuming that an additional tank has been established.)
This is difficult for me to answer truthfully without being direct.
If this were me, I would either not buy the angels, or I would buy a new tank and set it up for them [they have to wait for this, and a temporary 20g could suffice, or even a 10g]. I would never
add them to an established discus aquarium.
The reason for the latter is two-fold. First, the high risk of "disturbing" the discus. These are cichlids, as are the angelfish [I know you know this, just making a point]. All cichlids, regardless of species, consider the aquarium "theirs." Period. They may or may not tolerate "intruders," and this can be any other fish species coming in after they settle in, but with another cichlid it is intensified many times over. And in reverse the angels may be temperamentally troublesome; a territorial male angelfish can kill every fish in a tank in a matter of days if it so decides. We don't know the temperament of this pair because we don't know their history. Their past environment and care may have caused them to become real bullies; or they may be quite the opposite and thus subject to the discus aggression.
While we can make generalities about fish species, we all know that individuals can differ, and often this is due to environment. But we still know their inherent traits that nature has given them, and we cannot change this. My approach is always to assume what is "natural" will occur. And that means in this case not mixing them. I would not want to risk a tank of discus.
