Release Unlocked Cashflow spreadsheet to client

What would you do?
I have prepared an extensive cashflow forecast to include P&L and BS for 3 years for a client on Excel to be used formally in an application for a large loan. The spreadsheet contains linked formulas and pivot tables etc. After sending a locked copy over to them, (to restrict alterations by the client and to protect my own work and integrity), they are now requesting an unlocked version.
Would you release an unlocked version for others to amend/adjust after spending hours preparing it, possibly manipulating to 'look better'...?
Thanks in advance
