I would not recommend it. Simply because the forms of kanji, hence the types of radicals that "build" them, underwent many modifications and changes throughout the history of evolution of Chinese characters. Also, 85% of the characters are semasio-phonetics, so it will only confuse you. If anything, I would suggest learning major radicals while studying characters. For instance, a presence of 草冠 ("grass crown", i.e. grass radical) on top (crown) of the character usually leads to a conclusion that given character is associated with plants, etc.
