With the scrutiny banks are currently under, this would be a rather foolhearty move. Most major banks are publicly traded and thus have to report their financials to the SEC and to the public every three months. You have analysts at companies (and the federalones) who do nothign but comb through these reprots looking for discrepancies/improprieties.

Easier just to lend the money to the MCA or whatever and have no part of the day to day stuff.
