Yes, I don't see any issue with it.
As far as 'VAAI NAS – Full file clone' concerned, according to KB below, it is supported 5.x onwards and according to IMT all 9.x supports it. VAAI NAS Full file clone enables the Storage array host to make full copies of data (vmdk files) within the NAS array without using the ESX resources to read and write the data.
Starting from ESXi 5.x, support for NAS Hardware Acceleration is included with support for these primitives:
For cross-volume deduplication (IAD) : If this feature co-exists with IAD ? I don't see any issue here. Is your query .
Only caveats for IAD:
All volumes must be thin-provisioned (space guarantee set to None) for IAD to work.
IAD is not supported with NetApp Volume Encryption (NVE)*
*Starting in ONTAP 9.6, NetApp has included a new feature called NetApp Aggregate Encryption (NAE), which assigns keys at the aggregate level, hence encrypting all volumes within the aggregate. This not only simplifies encryption management, as there are less objects to manage, it also allows volumes to be encrypted and deduplicated at the aggregate level.

Cool i'll give it ago, waiting for 7MTT to finish, until then they are still on 9.5. Once on 9.6 i'll put aggregate dedupe, aggregate encryption, then try it out.
This would be similar to a SolidFire with it's global dedupe metadata disk. Savings no matter what volume the data is in hurah.
