Brady expressed her interest in buying the stadium outright for the club, and also stated how it should be generating money.
The former apprentice judge also criticised the stadium's current owners at a meeting in London.
"I think the London Stadium craves direction," Brady told the assembly.
"It really should have the commercial expertise it deserves. I don't think it is anywhere near realising its full potential.
"When we first wanted to move into the stadium, we offered to buy it. We offered to buy it, which meant we would run it, which meant we would have been responsible for all of the costs and that was rejected.
"That (buying the stadium) is certainty something we would look at. I think if it was to become a dedicated football stadium, with pop concerts, maybe the occasional rugby match, then that could be a seriously very good proposition. That might be something we are interested in.
"The problem for this stadium is the cost of the seat moves for athletics. That is what drains this proposition of all its revenue.'
Converting London Stadium into a football ground cost £323m when the original estimate was £190m.
And although West Ham pay an index-linked annual rent that has now reached £3m-a-year, the venue is still set to lose £140m over the next 10 years.
Asked if West Ham would be prepared to buy the stadium if it was offered, Brady said: "That's certainly something we'd look at."
about the current owners, stating that the stadium should be able to generate money.
There are also concerns that converting the stadium into a football stadium would go against the agreed London 2012 legacy plan, insisting that it had to stay as a state of the art athletics stadium.
