Is it possible to use land rover defender 110 rear dif with a land rover 90 front dif?

Is it possible to use land rover defender 110 rear dif with a land rover 90 front dif? Will it cause any probs when I try to use 4 wheel drive??|||Are the differential ratios the same? If not the 2 diffs would be fighting each other and cause binding in the drivetrain, with a big breakage soon after.
