I would say that invoking a dead someone for intercession before even being declared Servant of God (and I would personally say not before Venerable, the first declaration made by the Holy See) is imprudent at the very least, and highly inappropriate at worst.
I ask my deceased relatives to pray for me all the time. I doubt they will ever have a sainthood process, especially the ones who died Protestant. Of course I also pray for them, including having Gregorian Masses said for them. I don’t think God thinks my prayers are imprudent or inappropriate at all, why would he think that about a sincere prayer? And if God doesn’t object to my prayers, and the Church also doesn’t object to my prayers, then your opinion matters not.
