I found at last what I was looking for:
https://github.com/turtlepod/gt-bbpress-author
here is a “GT | bbPress Author Drop Down” that works like a charm!
It works for me in BuddyPress, with bbpress forums, WP 3.5.1

I could not find the plugin in the repository, just in github.

For non-specialists:
You have to copy the file content (that you see on the github page) in a new file, save it as a php, put it in a zip file on your desktop, and then install the plugin by using the “uload a zip” feature in your wordpress installation.

there is a plugin, works for me just partially:
https://wordpress.org/extend/plugins/orbisius-bbpress-enhancer/
the problem is, I cannot change replies-authors, but just comments (topics) authors. Otherwise, it works fine!

I tried to use the bit of code postet here above by Anointed.
I put it in the functions.php file of my buddypress theme.
It didn’t have any effect…

On the other hand, I found a plugin that does the job, but just partially:
https://wordpress.org/extend/plugins/orbisius-bbpress-enhancer/
(Orbisius bbPress enhancer)

This plugin works fine, but it allows me to change only the COMMENTS authors, not also the REPLIES authors.

(forums in bbPress consist hierarchically in: FORUM > TOPIC > COMMENT > REPLY)

I Would be grateful if any coding specialist among you would tell me what to do with the codes above, to get them working (for comments AND replies).

Congratulations! You have successfully registered a new site.

Hi, I have the same problem, but additionally, my buddypress does not install the new site. I just see an empty directory there, no wp-powered site.

I would be glad to get a hint from you! Thanks in advance!
