Not sure about the Aldecaldos going that far but pretty sure Panam would go with us through hell and back and see this entire thing through. Yes, even in space.
She literally drops everything at 3 AM to come pick you up, bring a tank and assault a friggin' Militech mining operation + Arasaka Tower, just to give you a chance at survival. And she does that for your V regardless of gender or romance.
So yeah, I think she'll have our back in the Palace, especially when romanced.
Plus she seems already pretty invested in helping you to begin with, by going through all her Aldecaldo contacts, no?
Why not introduce new female character and awesome romance ? why limit option to 1 if you can have billion choices. I rather have more choices.
