I think so but you might want to check out the possible implications of having the family home in one name and I'm not sure if Revenue take a dim view of a married couple putting the home in the sole name of the remaining FTB spouse. As far as I know it should just mean that if he died then you would have to take out probate whereas if it was in joint names this would not be necessary. However there could be other implications.
Remember that you (individuall) are still a FTB for owner occupier mortgage interest relief purposes for whatever remains of your 7 year FTB period.
