So I am currently designing a high-quality mortar set-up, and would like your guys' input. My goal with this is something that isn't ugly (most likely will look like a real mortar), and isn't a pain to deal with(not huge and heavy), and not incredibly expensive (I might plan on making and selling these)

sounds cool... it's always fun to think of ideas like this, but having a dedicated mortar team might be a bit tedious. Also getting a direct hit from one of your projectiles is a real possibility so that needs to be taken into consideration. Overall good concept there are fair amount of home made a professional made rocket propelled grenades airsoft systems and the like. There is a one mortar launcher on the market maybe you can get some ideas from it.

If your thinking of a high-capacity tank of either air or propane, you might as well build it to launch something bigger than a airsoft 40mm grenade. See if you can't rig a Nerf football that already has the "screamers" on them, them have some loud cap or blank cartridge that will "pop" when it hits the ground that could be your normal mortar shell. this would be internal, yet easily accessable to the operatior when you want to change out for the second game.
Maybe I didn't make my intentions entirely clear... the air burst will actually send a spray of bbs while still in the air and pointed downwards, and the impact burst will actually burst out a bunch of bbs. When I say high-quality, I mean it. No "pretend 20 foot blast radius" here

I know that some other people have talked about this at least the ground burst one, but I don't think anyone has tried for air burst stuff thats REALLY complicated to get right. You will still need to start out by building a launcher and picking out a type of projectile and THEN make them burst BB's when they hit the ground. I also recommend the Nerf howler as a platform. you can buy them relatively cheap they have stabilization fins to keep a good trajectory in the air and they howl which is semi realistic for an incoming mortar shell. You could also go with the pocket vortex:
