It'll probably sound fine if the amp isn't a total dogegg and the mic and PA are quality. We've got pretty good at making things sound... 'pretty good' in the 21st Century even with weird audio routing. It's not like we're still kicking around Carlsbro and Peavey stuff from 1992. I went to a cricket match with a live band between innings. The only thing I could hear, being in the top tier stand and side on to the stage, was the drums and the lead guitarist who mic'ed through the amp, so if OP is setting PA up for a cricket match then maybe it'll help?
