WI: a major Indian emperor in Castile?

WI a major Indian emperor reached Castile?

What OTL happened to the major Indian emperors:
Moctezuma II - contradictory accounts. By Spanish claim - attacked with missiles by his rebel subjects, died of wounds. By Indian claim - killed by Spaniards shortly before their escape on Noche Triste.
Cuitlahuac - died of smallpox epidemy
Cuauhtemoc - taken alive in 1521. Lived for 3 years a captive in Mexico. Carried along on expedition to Honduras, executed there
Huayna Capac - died of smallpox epidemy
Huascar - executed while a captive of the captive Atahuallpa, with Pizarro´s approval
Atahuallpa - openly executed by Pizarro.

So, WI a major legitimate Indian emperor, having been captured alive, is packed on a ship and sent to Castile, and received by Charles V?

Cuauhtemoc lived for 3 years a captive in Mexico. Practical opportunities to put him on a ship existed.
Was the option ever discussed by contemporaries?

What would have happened if it had been Atahuallpa sent through Panama to Spain?
 
They would had died quickly from local diseases.

But seriously, I don't see there happening very big changes.

It would be intereting if Christianized Mesoamrican royal/noble families intermarry with Habsburgs and other great European houses in some way and proudly celebrate their Aztec/Inca roots( The house of Montecuma hold on in Spain OTL !). Maybe Aztec references in the coat of arms.
