New Primary Ledger vs Adding a Secondary Ledger

Our ledger runs in currency A. We are considering a new business in another country that uses currency B and requires the accounting books be kept in currency B. We have already been told that running in currency A and translating to currency B after the fact isn't acceptable in the new country.

One option is to create a new Primary Ledger running in currency B. This would require new setups for all the other modules (inventory, AP, AR, purchasing, projects, etc.)

Would it satisfy a country's requirement for the books to be kept in currency B if we add a new balancing segment to our current ledger running in currency A, and create a Secondary Ledger running in currency B? We would set it up so that all journals entered to the new balancing segment transfer to the Secondary Ledger. We want to be sure because we have already been told that running in currency A and using revaluation/translation afterwards isn't considered equivalent to running in currency B, and Secondary Ledgers sound like they are doing the same thing
