Moreover, partner will bid more aggressively, on exactly the wrong hands, after 1N than after 2♦. He thinks we promise a bigger minimum for 1N. He may well take us to a weak 5-2 spade fit, or overbid thinking that his clubs will be more useful than they are.
Getting to the 5-2 spade fit would be a dream if we enter the bidding!

Stretching to make understrength unfavourable 1N overcalls strikes me as suicidal/fratricidal bridge at its worst.
That's what I think of overcalling 5 card suits at the 2 level when RHO is probably unbalanced.
