The only thing I can think of is instead of using the spacebar to trigger a turn-based mode, turn it into a pause button, and while paused to be able to activate or set any reaction. Still, it requires you to pause before the thing happens. Your mention is similar in the aspect of pausing but requires the game to do a check to see if you still have your reaction available and if you can use it in that circumstance which is a good idea to me.

Though the only problem with pausing in the game as it is currently is that multiplayer mode doesn't support it. A lot of the game's features for turn-based combat are also about fluidity and multiple people being able to do things at the same time if they roll the same initiative, etc.

They may decide to make the shield spell work just like hellish rebuke, casting it on your turn and making it a +5 ac boost until your next turn. This would be disappointing, but it is what looks like what will happen.
