Disagree. Once you get accustomed to reading kanji, and did not learn to visually parse (except very briefly as a young grade school child) nearly all of the words that you see regularly as logograms first, and groups of sounds second, the experience would be akin to reading English while afflicted with a strangely selective amnesia hole for entire words. Such that reading a word like 'shoe' would not instantly evoke an association with a piece of footwear but would have to be (admittedly very rapidly) sounded out letter for letter each time, instead of scanning the entire unit as a whole.
That's what reading a word normally represented by a familiar kanji character but "expanded" into hiragana feels like, and slightly more pronounced if it's, for some hipster reason, written in katakana.
