I just had a look at the delphi in the old and new

2015 uses TStylePickerDialog
2016 use a new form TStylzDialog for the new picker but TStylePickerDialog
form is still in the code
so yes you could have an option to call on TStylzDialog or TStylePickerDialog

If you go to preferences and check run multiple instances - just above the OK button - you can run the old picker 2015 alongside 2016
just copy the name you like then paste it in 2016

Hope this helps
