It's only frozen at the caps because the caps are something like -200C

well, when all the liquid water boils out of the plants, i'd say that is a problem. unless you construct greenhouse facilities on the planet, and again this goes back to the cost factor.

Pressure will fuck up the vascular systems of the plants, low pressure means theres nothing to push the water through the plant, and there would be issues with gas exchange as well.

Still brings more water to mars and if you focus the comets to hit in one area it could heat up the ground enough to melt the water.

You end up with a nice water filled crater lake.
