The £10 delivered Nisan Micra blower motor has arrived and the pic shows them side by side , My thoughts are that the Micra blower will fit but it will be a very tight squeeze - its obvious from the pic the increased surface area of the fan so the output will be significantly improved and the air might even hit the windscreen .   It wont be a case of simply opening the aperture equally to fit the Micra blower as there isnt enough room on the left hand side inner skin, so much more fettling on
