I only need it for size comparison for other imperial cruisers and to maybe make one with an underside hangar and correct key points like bridge and communications. Don't really feel like going through all the steps to reverse compile it to work in XSI and I figured someone has to have done it by now for whatever reason.

I don't have it in a converted format, but it's not a whole bunch of "steps," it's a one-step process:
