Seems to me, certainly for 25Ks and above where ATP rankings will be more often held ( and maybe just generally ), that the ATP ranking is most certainly the principle one and the better indicator of players' levels so maybe bracket the ITF one.
And similarly for WTA and ITF rankings.
Anyway a suggestion, if arguably not that biggie a one.
