TO expand on my answer... Front fork stands would have the bike balanced on the fork tips. Not wide enough apart to be stable and not very stable anyway when the bike is being moved around, as in putting it up on the rear stand. You'd dump the front off the stands guaranteed.
With the triple clamp stands you'd be trying to balance the bike on the pivot point where the pin goes in. That wouldn't be stable either without the rear stand already in place. If it swayed either way it would dump.
Not a good idea at all in my opinion. Also, Pit Bulls come with warning notes not to use their front stands without the bike being on a rear stand.
