Can you mix LPG and NOS?

Is it possible to have an LPG system installed and a NOS system at the same time and use NOS whilst on LPG?

Thanks for the replies. I am talking about Nitrous Oxide and not the fuel additive. Not looking to actually have such a setup. Just an idle discussion in the office about whether such a setup would be possible.
