From KLAS off of 07 you could swing to the NE and try to hit lake mead. Your only other options if you want to try and land a T7 would be US93 or US95 to the S SE. Both 4 lane highways, straight, with full shoulders. But you are looking at a 35' wide runway ( with hard packed earth on both sides)
You might try for KBVU (Boulder City NV), but the runways are more suited to a king air or small jet.
