You can re-amp it live through a power amp and FRFR and/or send it to the FOH system. So the cheapest route for a "no PA" like you are asking about would be get a couple powered monitors to become your two wet cabs. Or possibly just one (but then no stereo) to just use the correct XLR out that has the 'twinned' track on it to get the effect of a second guitar player. Although I'm not sure that would come across compared to the two XLR outputs contrasting to each other you would have your regular guitar cab contrasting with the one DI output...might not deliver the same effect to the listener without the same-but-different reference sound.
