I misunderstood you then. I thought you meant that you could achieve better resolution than the X1 without stitching.
A 2000 dpi scan of 4x5 should yield 80mp - meaning you would need stitching to match the resolution. This is without taking the D800s true resolution into account, which should be quite a bit lower than the stated 36mp. With a really good lens (the X1 uses a very high quality Rodenstock lens) and stitching you should be able to match the resolution of the X1, yes.
This is not theory; I've tested it. A 9 image stitch of a 4x5 image (the above shot of the boat is a 9 image stitch) is as good as the X1. Or at least not discernibly worse.
Re: stitching, I generally don't bother. For me, the advantage of DSLR scanning is its massive advantage over consumer and prosumer grade scanners (flatbeds, for sure, but also the Coolscans and Plusteks), rather than its performance with respect to a $15000 X1.
Most of the time, a ~30MP DSLR scan of a 6x7 frame is more than sufficient, and offers greatly superior results vs anything I can get for a comparable price.
I'm all in on DSLR scanning. In my view, it is 100% the future for HQ film digitization. Witness the $$$ Capture One Heritage/Phase One product.
