You can force-install RPM packages using the busybox tool rpm (or rpm2cpio, but that doesn't work on the latest RPM format). Debian packages can be turned to tar packages with deb2targz, it's available from BLFS.
Why, that's another question. Using these on your own system is fine, but please don't submit extensions gotten from other distros' binary packages.
PS: I've used the RPM facility once: to get Lacie's LightScribe software (only available in 32-bit RPM IIRC). It's a shame there's no OSS software to laser-label discs
