i would be concerned that 53 IBUs on a dry 3711 beer is going to be... bracing. as long as you like strong bitterness, go for it. there is going to be little to no residual sugar left, so you'll get the full brunt of that bittering. "true" IPAs aren't as dry as 3711 brews so they have a little sweetness to balance the bitterness.
regarding "53 IBUs, so it wont be the Hoppiest IPA" - don't confuse bitterness with hoppiness (i.e. hop flavor and aroma). you can make a very hoppy beer with no hop taste/aroma, and you can make a beer with little bitterness but a ton of hop characteristic. in your recipe, you'll be getting your hop character - hoppiness - from the late addition of Sorachi Ace. the magnum is a relatively low-flavor hop, and after 60 minutes of boiling there will be hardly any flavor or aroma left.
