Larry is tired. Frankly, after all the effort he has spent on PPP this last week I'm surprised he isn't sleeping. :-)
I read the OP as saying that he happens to have an existing plan that is balance forward, to date. They want to move to individually directed with daily recordkeeping with a twist. Instead of providing participants with a menu of mutual funds he wants to create a set of investment options where each option is professionally crafted and managed by an investment professional. Setting aside the fact that this design is very difficult to implement (from a fiduciary perspective) there is nothing wrong with the concept. I would be surprised if many of the recordkeepers in today's market can accommodate this construct. Instead, a big investment house is more likely to have created proprietary funds that are close. In short, the OP is trying to re-invent something which already exists. And if they were the size of, say, Boeing, they might just find an investment house/recordkeeper platform willing to create exactly what he is looking for. Otherwise, the fiduciary risk to implement this on his own is off the charts and makes no sense in today's marketplace. I'd be interested in @Peter Gulia's take on the fiduciary issue.
