The Gk are no combat psykers, they train to use their psycic abilites as shield against daemons, and their offensive psycic quialities are of little use, if they are slain before they even know wha happens to them. Their training isnt better than the training of any other spacemarine chapter. Its even shorter and less selective. Custodes are trained to overcome psykes and superhumans alike, as individuals they are matched by nothing within the Galaxy exept for primarcs. They are the emperors best. Period. They are duelists, assasins, Bodyguards, each of them is an Army in his own right. A few of them where killed by the gal vorbak, but these guys where practicly deamon princes, they where not only possessed, they where transformed into demi-deamons, which is a unique thing within the whole W40k Universe. As daemon hunters th Gk are unmatched, they are waepons againt those who are touched by chaos, the same touch of the warp, that augments a chaos champions powers, becomes a waeakness, if he faces a gk. But against a custodian, this training is of no use, a Custodian is about as dangerous as a Chaos General or even a Daemonprince, but not touched by chaos. the Gk are a highly specialized force and the best in their buisiness but the Custiodians are Masters of al kinds of combat. The strenght of  the Gk is their bond of brotherhood, not  their psycic ablitys. That is the one thing  Astartes have and Custodians have not- they do not funtion as individuals, the funtion as a Unit. Within a duel not eve one of the most elite Gk would stand a chance agains a custodian, he would be slaugtered within seconds, beause he is far slower, weaker, inferior in martiall skill and simply not trained to be a single combatant. Thats what Custodians do best. In a battle, however the Gk would fuction better, as a Unit. If that would be of use, without the superior Numbers they need, i can not say. If the Custodians would be able to leave the emperos side, probably they would be the daemonhunters. But i believe they are physicly incapable to do so for too long. They are engineered to stay at his side and can not help what they are. Ore does anyone think the most deadly force within the Imperiums History would lurk in a palace and see their mastes work be flawed if there wasnt a practical reason? "Their place is on the emperrors side" I think that is not only a silly tradition- they simply can not leave his side. If it where different, what would have kept malcador from recruiting psykes, enhance them in the same way as the custodians and train them to kill daemons? The Gk showed up, for the first time, when the Custodians had to disappear because the G.E. was disabled. I think they are some kind of replacement, they are meant to be the Emperrors sword, where the Custodians are his shield. And both Units are perfect within their Job. If you let them clash the situation decides who wins, the whole idea however is stupid. that is something, that would never happen.
