If nominees are impractical depends on the Jurisidctions - Jurisdictions with British Common Law can work good with Nominees - as well as some Jurisdictions that are specialised with Nominees like Cyprus.
However getting such structures banked gets harder and harder each year and with the upcoming UBO register not only in the EU but also along most common British Common Law countries in the Caribbeans as well as in the Channel Islands - the nominee usage will be pretty much dead.
So better get yourself a setup in a jurisdiction without any publich company register or public UBO regsiter plans like the UAE so that you are fine till a date where the public UBO register will be a global adopted requirement - we will see this for sure within the next 10-15 years and till then ride the wave till the end with the UAE.
