+1 for Bikini Atoll with Master Liveaboards. Trimix is available for CCR (not for OC) and whilst the O2 is only 92% and they won't boost above 150bar, but it never stopped us. We had a solid 100min on the Saratoga, 190min dive all up, it gloriously warm water. Sorb cost a fortune, but with 4hrs in the water every day it was worth, used the whole drum. If I recall it is a mod-2 minumum cert, the sand is 52 or 53m with zero current, most of the wrecks are +45m to see much detail. Guides are optional, as is penetration.
Vanuatu, Espiritu Santo, the Coolidge with Pacific Dive are also rebreather friendly. Sorb can be bought by the kilogram, mixed-gas blending to spec. O2 is only 96% but its more than good enough. We also did Million Dollar point and last discussion with them they were adding deep wall dives. Lots of dives based on cert, but mod-2 is best as the sand is about 65m and the engine room dive was mid 50s. All dives are guided by Vanuatu law, but the guides are superb so don't sweat that aspect.
