If the washers are crushable, there is probably a specified way to tighten the nuts. Most likely there is a particular amount of free travel of the clutch fork. If there isn't it seems like there should be.
I suppose you'll have to see what the pedal feels like. You may prefer less free movement, or you may not. However I suggest you make sure there is a reasonable amount of clearance - you would not want to have to pull the shaft out again without a good reason. Presumably you could put additional plain washers into the stack, or replace the original crushable washers, if it looks a bit marginal.
Bear in mind that crushable washers, when they are used, have a purpose. Usually the purpose is to ensure that there is sufficient force on the clamping nut to keep it from coming loose. If you undo the clamping nut then do it up again without crushing the washer further, there will be less clamping force than there is supposed to be, and the clamping nut is at risk of coming loose in service. The only correct procedure is to replace the crushable washer each time you dismantle the component. Those of us who are cheapskates sometimes examine the washer to verify that it has room to crush further, then pack it up with plain washers so that it can be returned to the original overall dimension while crushing the washer further so as to get enough clamping force.
