No, I don't think anyone is working on this.
Don't call it a "Brokerage Statement", though. That's a document from your broker telling you what they think is in your account and what transactions occurred over a given period (usually a month). It's one sort of source document that you'd use to reconcile your Gnucash accounts.
Some immediately obvious pitfalls:
* There are (at least) 3 ways of accounting for realized gains/losses: Splits inside the sell transaction and splits outside of the transaction using or not using the "lots" mechanism.
* There is no good way to tie dividend or interest income to an investment.
* Some people (incorrectly under US tax law) book commissions and fees as separate splits to an expense account instead of netting them into the cost/proceeds.
* There is no standard way to account for covered options.
* There is no standard way to account for pass-through entities like S-corps and partnerships (limited or otherwise).
* It is for most users a manual operation to update prices. It *can* be scripted, but few Gnucash users have the technical ability to do so.
It's not going to be easy. Searching Gnucash Reports in Bugzilla for "investment" || "portfolio" || "stock" in comments returns 23 open bugs.
