I don't have anything ground-breaking to add, but... I've found that a pair of quality neo-loaded 112 cabs or 210 cabs can handle almost any situation - be sure to check sensitivities on them if you need to produce volume.
the kemper+ speaker idea is also a good one.
However, the root of this problem is the lack of PA support. I've played small clubs without PA and it was liveable, but I'd never do that for a festival. I want our band to give a quality performance, and that means we've made sure to have all the equipment we need for ourselves, and know how to setup and use it. Any decent venue should have FoH capable of mixing in your bass. Makes me wonder what they do for kick drum, just let that die in the air too?
fix the PA issue and you'll be fine with those Elf's for stage volume I'd think.
