This is actually quite a good idea. If you read on the meteor heads page, it says that it is possible to limit spawning with large amounts of water.

"They seem to have a lower spawn rate when you are in a Meteor Biome which has landed in or next to the Ocean. This may be because, although they can travel  through water, they perhaps won't spawn  in it, ergo having the meteor near or in water reduces the number of directions Meteor Heads can come from"

By covering 3 sides of your screen completely with water, it is potential that you could make them spawn only from the remaining side and thus be able to set up traps to kill only from that point, much like your 'funnel' idea. This is untested and it only says that it perhaps won't spawn in water but it has a good chance to work
