I have never done what you’re suggesting, so this is purely a guess. The curve of the box bottom looks pretty tight. My guess is that the filler wouldn’t tolerate the bending. You might want to do a test run to see how it fares. If it weren’t for the bend, I don’t think you’d have any problem with filling before the glue-up.

My $.02.

Have your say...
