The quick answer is no, not from Shimano. Biggest you'll find is 44T

The longer answer is maybe from some other aftermarket supplier like Real, etc. Plus you may find some one that does custom for trials and DH guys, as well as cross. The big problem is a lack of stiffness - you have a large CR but a smallish bolt circle and this leads to flexing. Having checked out 'cross races and the machines i would think that compact drive would still work with a small enough cassette. It is unlikely that you'd top out with a 44/12 in a cross race. However, if you wanted to use the bike for other things then you might. Why not get a road crank online - they're fairly abundant and cheap.
