Imo not suitable for an Irish red. Too much (good) flavour in this. Irish red derives it's colour from roasted barley, not highly kilned malts. Even adding crystal is debatable, original thing would be some UK pale, mo or similar, plus a dash of roasted barley.
However, red-x shines in everything American. Red ale, red IPA, everything with strong hop accent. Probably red Belgian something would also work well.
.... I mean at the end, of course, you can brew what you like and I'm pretty sure that a smash with noble hops and a clean yeast will yield a pretty tasty beer it's just not what would be described as an Irish red in Ireland.
But on the other hand... I had American red ales in Ireland that were sold as Irish red, so.... Nobody actually cares
