Eiji,

I'm a little late to this discussion and you may already have built your door.  My experience with Mahogany doors is that if using Honduras Mahogany it may not be light as you might think and I have built several out that material although, they were exterior doors 1 3/4" thick.  I have a Domino Joiner which I love but, a door that heavy is not a suitable use of the tool IMHO.  The doors that I have built have 8" top and bottom rails and a 6" lock rail.  I have used twin haunched tenons 4" deep into the Styles and used Tidebond glue for the joints.  I also installed ball bearing hinges for smooth operation.  

Jacko,

Ive built many. I prefer to use 1/2" slip tenons for exterior doors but that doesnt mean multiple custom domino joints are not strong enough.

I am finishing an interior arched top door and used dominos for part of the joinery and dowels for others. Unfortunately Festool does not have a big domino for doors yet. When they make it I will buy it immediately.
