Xenos Rampant is not designed for lot's of vehicles, so you would need to treat the AQMF units as infantry. Shouldn't be an issue for the tripods as 1 tripod could just have multiple wounds, but I am not sure how it would handle the Humans with their mix of infantry and tanks.
Could it work? Yes. Will it work well? I am not 100% convinced, but am open to see you try. I also have a decent selection of Martians and American troops.
Xenos Rampant (as well as a few other generic Sci Fi games) can use the Martians really easily as multi-wound units against various models. I have had mine fight Space Marines, Mobile Infantry, Gangsters, and others.
