What will happen is - you will eliminate a lot of play...but you will additionally introduce a whole lot of stress on the brace mounting point. If you have the version that's mounted using just two cover bolts - I can imagine that being a potential problem. If you have the version where you have an additional screw on the diff cover - that might be better, provided that the mentioned screw doesn't go to ****.

I think that altogether - it's a bad solution and you should change bushings.
All of this. ^^

A differential brace is a bit of a hack created as the lazy mans way to mitigate differential movement. Will it massively reduce movement in the rear differential? You bet. But like mentioned in the quote above, you are now focusing nearly all the stresses to a single mount at one corner of the differential. If you truly wanted a solid mounted differential, the proper way to do it would be to replace all 3 of the original mounts with solid bushings. This would keep the stresses spread out rather than focused at one bracket at one corner of the differential.
