Intercept Strike + Shield Block is it possible?

[YuriP]

Let us consider the following scenario. You got Quick Intercept and you use Intercept a Strike to protect an ally and now due you will get the damage you can use your normal reaction to Shield Block.

First. This is possible? Intercept Strike has the trigger "An adjacent ally takes physical damage" while Shield block has "you would take physical damage" in the trigger. Even being similar are they different triggers right? So can they used together to basically sum the resistance and hardness to diminish the damage that you will take?

Second it worth? To use 2 reactions to defend from just one Strike to make it basically works like a Shield of Reckoning is not the best usage of reactions economy but maybe work to call the enemy attention without need to use Taunt once that will be difficult to take you down with all that DR and probably is better to the enemy to focus on you instead of attack your ally.

I don't see why it wouldn't work.

First the ally takes damage, you use a reaction and change that.
Then you take damage, you use a reaction and change that.

If it's worth it or not depends on a lot of factors:
Maybe you want to keep your reaction open to intercept another foe if your ally is squishy or low. Maybe you are low and want to keep yourself healthy. Maybe your turn is coming soon so there would be less opportunities to use your second reaction, and etc.
