I've considered this as well, probably because I also get a 4% employer contribution automatically once a month regardless of my contributions.
The only restriction on our company plan is maximum 91% of salary, so as to provide sufficient funds for social security, medicare and state disability.
I already employ a dollar value averaging strategy; so that all contributions go into a money market fund initially. I then transfer a set amount three times a year to achieve a self-chosen yield target (currently 6% p.a.). If my underlying stock fund is beating my target, I transfer the excess for that four months to the money market fund. Otherwise, I transfer only enough to meet my goalpost for the third of the year to the stock fund (i.e. sufficient to ensure 2% growth over the past four months).
So, it should be possible to front-load and fully fund the money market fund. I started getting the catch-up contribution last year, so it's $22.5 K for me. These funds would be in place about the time the first adjustment milepost surfaces on May 1.
This has the added advantage of taking money off the table when stocks have been on a tear, as they have recently. I just wish the money market fund had a bit better yield for some additinal upside.
