The Nikon and Canon 1,4 lenses are ver nice on a speed booster on an X. Otherwise they function very like a 135/2,0 lens, which is even more interesting. The 2,0 speed of the Fujifilm will of course make the 90 act like a 135/2,8, which is still decent. The funny thing is how big this lens will be. 90/2 lenses are big. 135/2,8 lenses are not. But because to achieve the equivalent speed/etc., the 90 will be big.

The apparent angle of view of a lens changes when the size of the recording medium changes. That's why the 90mm lens on an APS-C sensor will have an equivalent FOV of a 135mm lens.

The aperture of a lens does not change, ever. An f/2.0 lens has an aperture of f/2.0 always.
