If you're using a hammer drill after the chaser, what's stopping you from having 4, or even 5/6 blades in your wall chaser? It will make the hammer drill part easier.
I understand that some people use a bolster chisel after the wall chaser, so 2 blades is probably ideal. But if you're chasing into non-brick materials such as breeze blocks or stones then surely the more blades in a wall chaser the easier the job is?
I just tried fitting 4 into my cheap Screwfix Titan wall chaser and it accepted them. Only problem is they were undersized angle grinder blades as I don't have 4 wall chasing blades
