We have not a slightest indication that he did have this kind of thoughts.

And it would make it a little unfair on his son

It has been "unfair" in exactly the same way for every King's heir since the times of Tar-Ancalime, that is for about 5300 years. Yes, that long.
Once an exeption had been made for Valacar. Result: civil war, the loss of the Capital city Osgiliath, the loss of the Palantir, the loss of Umbar, the death of many in the King's line.
Aragorn was not the kind of ruler to come and change time-honored old customs: exactly the opposite, in fact.
