WI no Nevada Territory or Nevada Territory kept at original borders?

Nevada and its state-hold has come up in two recent threads.

Doing extensive research (spending four minutes at the Wikipedia page on "Nevada"), I discovered that the Nevada Territory was carved out of the Utah Territory in March 1861. However, the boundaries were different from the state that was created in 1864.

The Utah Territory never contained what is now Clark County, which now contains Las Vegas and over two thirds of the population of the state of Nevada. This was part of the Arizona Territory and remained part of the Arizona Territory. Congress transferred it to Nevada to punish Arizona for its pro-Confederate leanings (also see "How the States Got Their Shapes").

Also in 1861 the Utah-Nevada border was somewhere further west of the eventual 1864 border, though as this strip is very lightly populated this is less important.

The state was created in 1864 as a number of sleazy Republican moves to boost the number of Republican Senators and electors, that, along with the Civil War itself, pretty much wrecked federalism and boosted the number of low population Western states, along with West Virginia which was another one of these moves. Like the creation of West Virginia, the creation of Nevada was illegal but they really thought they needed those three electoral votes.

What happens if they don't bother, and keep Clark County in Arizona and the rest of the state in Utah? Alternately, the Nevada Territory is created using the 1861 borders and never is expanded and becomes a state (creating the state within the 1861 borders was too much even for the GOP at the time)?
