Standing next to a sub probably works just fine! That's essentially what I'd do if they'd let me use my 15" cab.
80 grand got them a huge board with lots of monitor mixes, Roland V-drums, racks of gear, a digital snake, tons of power amps to run those little 12" mains, etc.
Yeah, absolutely I could've put together a much more practical and better sounding set up for a fraction of the cost. Oh yeah...of course tons of wireless mics so the mics can just stay mounted in stands anyhow. It's just sad how so many churches have tried to move to this way of doing things. If you need so much control over the musicians maybe those musicians shouldn't be playing. Does the church trust them to do what they have worked hard to be able to do skillfully? If so, get out of the way.
In that case I'll repeat my earlier statement "That church doesn't actually want bass".
