I've been looking around at 10 bolt alternatives for my 1/2 ton; just thinking into the future.

I found one 14 bolt upgrade that is a "drop in" including 6 lug axles. Not sure if you got 6 or 8 lug. It is not cheap. From the pictures shown these things are HUGE. On my stock height 1/2 ton the beast would stick out like a sore thumb.

Not sure if this helps you much, but here it is...

Please disregard if you already know about this.

This joint does have a 10 bolt to 12 bolt upgrade, but not for trucks. Too bad.
