That is indeed possible.
sudo apt install yum*
sudo apt-get install yum*
after this, add your favourite or required repos to the system like
rpmforge or any other repos by usual way with
yum command in place of apt.
Repo is just a place from where you can install or fetch the package or tarball so no matter what you use in whatever system you're using. But this will be the case that some programs will be configured automatically according to RHEL config. This config thing is just my assumption, not sure if that is happening all the time. But we can change it anytime.
Like in some Linux destros, Apache or PHP installed to
/opt/. Where in cross repo usage (as in
yum used in ubuntu instead of
apt-get), it might take change as parent package provider config rather than system's native config tradition.
