If the can lights are already installed, then he obviously installed the wiring to them before the drywall went up. That's good. You need to find out if the trims you want to use can be used with remodel type can lights. If they can, then that is the type of cans he will want to use to replace the new construction cans he already installed. It shouldn't be very difficult to do. It could be moderately difficult to remove the existing cans from below the drywall, but if there is access above the drywall, he can remove them from above and replace with new construction or remodel type cans. Also, your electrician should be aware of the IC (insulation contact) rating necessary for can lights that will come into contact with insulation. If the can lights will touch insulation, this rating is an absolute must.
