Rockshox and Fox seem to 'just' fit going by pics on MTBR. I'd worry about what would happen if the wheel got knocked out of true. Some people have dremmeled their forks to give more clearance Not something I'd trust myself.
Charlie the Bikemonger has some Blutos fitted, there does seem to be an interference issue with the fork crown and the down tube, but unless you have a lot of crashes that shouldn't be an issue.
If you can find a set of Maverick DUC32s they'll fit with a bit of judicious fettling. I picked up a set including a wheel for £150 on ebay. A couple of hours in the workshop making the bits I needed. Luckily my existing front wheel has a Hope Pro II hub, for which you can buy a Maverick axle adaptor.
Here's the thread I started about what I did to make them fit: Kramp'sus thread
The headtube is a bit short on the Krampus, so I needed to make a slightly longer steerer nut for them. I also made some longer travel reducers to eliminate any possibility of the tyre hitting the crown.
