Hello Nathan,
I have a similar arrangement with mail from an old and heavily-spammed address forwarded to a more recent address. I do not believe the old receiving domain can be suppressed, nor should it be - it is, after all, the delivery point of the spam and the critical part of the 'evidence' for spamming ISPs to investigate and eliminate the spam source, should they wish, which is the whole point of reporting.
Another point - sooner or later (and many times thereafter), no matter what you might do, that khg-heidelberg.de address will be forged as the supposed sender of spam messages. If you want to report the hundreds/thousands of misdirected bounces to the khg-heidelberg.de address which will follow, in the faint hope of 'educating' the clueless mail administrators responsible, the domain/server certainly cannot be suppressed. And there are a great many clueless administrators who urgently require education - including some in the .de TLD, co-incidentally.
It is better not to report at all, if you have concerns, but in my experience it will make no difference to the amount of spam reaching the khg-heidelberg.de address. I used 'mole' reporting for many years (which is to say no actual reports went to the spam sources) but the spam increased anyway. Once that address is on the spammers' lists it stays there - even if the address is abandoned, to give you some idea of their practices. I see that (rejections for abandoned/non-existent addresses) all the time in the misdirected bounces I receive when it is my address that is forged.
When you report you 'feed' the SC blocklist and this provides a way to keep spam out of people's inboxes (just in case, reading the above, you wonder what is the point of it all).
