Bipolar question ?MOSFETS

I'm tinkering with the idea of building a coil driver
using a pile of MOSFETS

At work I work on switching power supplies that use
MOSFETS to switch as much as 500W at as much as 90%

MOSFETS have on resistances as low as .01 ohms
and off resistances > 10Meg

Has any one looked at using these things to drive a coil?
