There's no need to keep

if the speakers should really be placed correctly for 5.1 at the friends living room at
the moment.
If possible I would prefer to replace them in a way that's good for
ambisonics.

Ambisonics is really every channel with the same priority and use-case. It
will not matter whether you use the set up with "front" at positiv-x
direction
or 130° rotated around the z axis and 30° rotated around the x axis (when
using a full 3D rig). It will sound all the same. And the speakers in the room
have to be set up for this.
Also the speakers are all supposed to be equally away from the listener for
best performance

IIUC 4 speakers could be set up in a quadrate with "front" at positiv-x
direction and the listener has to be in the middle of the quadrate.
Maybe there will be 8 similar speakers and amps, but regarding to the
sound card the limit is 8 channels. I guess somewhere on the ambisonics
website there will be some text and graphic about such setups.

Yes. Fons ships an ambdec configuration for playing in a 5.1 setup (it
is not optimal because the back speakers in a 5.1 setup are too far
apart but it works - I use it at home). Of course it assumes that the
5.1 setup is correct. This link has a diagram of the speaker angles:

-- Fernando We are not talking about 5.1 or 7.1 here. These
suck big time.
We are talking about ambisonics vs. binaurals vs. simple stereo here!
Ok, I noticed this.
Fon's AmbDec is the player for the files from
http://www.ambisonia.com/?!
I guess a friend who lives near to my home has at least 8 outputs for an
Envy24 sound card and at least a JBL 5.1 setup, so the 5.1 speakers
could be used for a minimalist ambisonics.
