The only way to insert additional configuration to the VirtualHost
definition is to overwrite the file completely, basically sending the same
file with different content into the exact same directy, this is how I
managed to change from mpm_prefork to mpm_event, although it is another
file that the only content is the mpm configuration so it was quite simply
to overwrite. For the wsgi file, it is a bit more difficult since it
contains a lot of configuration settings where some of them are populated
automatically from the provided amazon config file and the auto deploy
process

Development and production use the exact environment, the only different is
that production is deployed behind a load balancer, but they are the exact
same machine setup through amazon elastic beanstalk deploy, so all versions
match, of pretty much everything.
I believe it is possible to install any additional package as long as it
can be installed through 'yum install xxx' and it is available given
ubuntu/aws repository, I don't know exactly where the packages from when
installed that way but I have had cases where some packages weren't
available. For next step, uninstall mod_wsgi and re compile a new version,
I don't think that can be easily done.
Basically you are given a config file that can contain a list of sequential
commands executed from the root directory of your app, plus a few kew/value
settings that are added automatically to the wsgi.conf file (like the
WSGIDaemonProcess process and thread values)

I believe what you say about using my own VirtualHost definition would be
the same as above, simply send my own version of the wsgi.conf file (which
amazon uses to set the virtual host and all wsgi settings) overwriting the
existing one but I'm not 100% sure it can work since I don't know how
amazon generates that file from my conf file, the order can be that it is
created after all my commands have run, so my attempt to overwrite it might
fail.
The amazon httpd.conf file indeed uses:
Include conf.modules.d/*.conf and
IncludeOptional conf.d/*.conf
The complete wsgi.conf file looks like this:
> LoadModule wsgi_module modules/mod_wsgi.so
> WSGIPythonHome /opt/python/run/baselinenv
> WSGISocketPrefix run/wsgi
> WSGIRestrictEmbedded On
