Could you build this?

Partial A container format and tooling for NX dumps is codeable, but getting the format right depends on specialized knowledge of Switch file structures such as NCA and NSP/XCI. Clean-room work also requires careful reverse engineering.

What it would actually take: Building a usable format needs a parser and writer for the Switch file structures, along with validation and checksum handling. The hard part is knowing the formats accurately, which requires reverse-engineering expertise and access to sample dumps. Legal review of the clean-room approach may also be needed.
