You could very easily find the old Pueblos in Arizona, particularly the Grand Canyon and Kayenta (steady water, variable biomes) when the Spanish invade/create New Mexico, either as they come in or after a revolt.
The Hopi who eventually established Hotivilla did this temporarily in the early 20th century when at odds with the US government. The Pecos similarly moved to Jemez when their community faced threats from Plains Indians.
Alternately, the Utes could have expanded into Navajo Land and probably adopted many Pueblo Clans like the Navajo did (30+Navajo clans have Puebloan roots even though they are assimilated) creating a hybrid culture much like otl Navajo.
New Mexico (the upper Rio Gande Valley) would most like be more Spanish/less Pueblo or overrun by invaders from the Plains. It is possible New Spain would end at El Paso.
