I agree with much you have to say, but I do not see that Rachmaninoff allows his personality to overwhelm or negatively affect the way he plays other composers. From what I've heard, he (mostly) accuratey translates the essence of other masterworks through his playing. What is so intriguing about Rachmaninoff the pianist is that he thinks as a composer when he plays, always, but not necessarily as Rachmaninoff the composer; His interpretation of the great masterworks shows an impeccable sence of timing and structure, which can be found in his compositions, he is not a pianist of great spontaneity or risk (unlike Horowitz), a quality which is certainly reflected in his constant return to Russian romanticism in his own compositions, he skillfully creates glorious melodies, which, when intelligently listened to are not, of course, the saccharine lilts they are often made out to be, and similarily plays the melodic lines of Chopin with startling restraint and taste---- This is not an argument that Rachmaninoff the pianist overshadows other composer's intents with his own, rather that he combines the best of both worlds, and in the process, engages in a unique dialogue of one composer creating through another.
