Carpenters: Can you help me with some nested pocket doors?

I’m trying to add some nested pocket doors, and I figured I’d just google myself an answer, but alas, either my google-foo on this subject is no bueno or… there isn’t any such thing.

So, here the problem. Trying to add a 42" pocket door, but there isn’t enough room in the wall, so I’m thinking 2, nested 21" doors (actually, slightly larger to add some overlap). You pull out one door, it latches onto the other door, and there you go!

But I figure this is probably a little tricky, and was wondering if anyone had experience with this and had an advice to offer. Is there specialty hardware designed to do this (I assume there must be, or I have to fabricate something myself).

I haven’t used this particular hardware, but I have used other Johnson pocket door hardware and it is very good.

Thanks. I think that’s what I’m looking for!
