We have done many AHC Sahara's but the ideal is 40mm, with the factory AHC shocks so as not to top them out often.
Remember it self levels so a coil sprung truck with 150kg + gear isnt going to be exactly 50mm lift any longer either, so 40mm works out ok.
Its a little complicated in the process, and if you get it wrong, the shock valving doesnt work, and its like driving a coil sprung car with no shocks, because the height sensors also control the valving of the shocks.
We have also stripped many and fitted conventional set ups, mainly our own specific Bilstein Platinum set ups for the 100, because early and late components from 98 on Lexus, werent as reliable as when Toyota chnaged to KYB parts in 2002, so selling on late model parts when removed to someone who needs an accumulator, or shock, is common, with the ones we strip the AHC out of.
Ride height of one we did, on one of our trips Transcontinental railway, Canning Stock Route, Tanami, back to Alice, and across the Simpson, Walkers Xing, and home. [remember fully loaded for canning trip with Kaymar bar and long range tank, winch and bull bar]
But I think you will be better off with this set up
