Your opinion about creating new accounts, FSV and legal statements

Hello friends.

I was asked to cretate a managerial statement with New GL accounts for managerial postins only (postings on these new accounts can not influence balances of legal Balance sheet and P&L).

Dou you see any problem if I create those Gl accounts in the same Chart of accounts used by the legal staments (balance and P&L) and include them in a new FSV?

Thank you,
