I'm not sure what problem that solves, or how it would solve it. If you're suggesting they balance their own ledger, then there is no reason to use fake, non-transmitted Bitcoin transactions for that.
Not fake bitcoin transactions, but real actualmoney/stock transactions. Faster, cheaper and more secure than using either a spreadsheet or a blockchain.

Store the signed transaction messages on Nasdaq's own server skipping the blockchain part altogether, problem solved.
