It may or may not simplify your installation but the price seems very reasonable. Not sure how much shipping would be to this side of the pond (to the US).
I am considering a similar DIY ITB setup to swap a 2.3l Duratec into a 63 sunbeam alpine. I think, however I am going to use a 3rd party ecu and ignition system. But, if your swap with the stock ecu and egr stuff turns out OK, I may try that path. I was thinking, to use the existing injector ports on the suzuki ITBs for nos fogger nozzles, so I am unsure how I could plumb the egr.
