New kanji learning technique.....possibly!?

Ok so im nearly at the end of heisig RTK1 and i was thinking what if i was to group the kanji i know together into readings? I mean now i know the meanings of the kanji and how to write them i could group all the ones with similar readings into Anki and then just memorise them as a group with same sounds but different meanings?? Surely this will speed up learning the kanji? Is this something i've just made up? Do you think it would work?

It is nothing new and in my mind is similar to learning kanji by radical since a lot of times kanji with the same radical have the same readings. But, As to whether it would work or not, I would say most definitely. Indeed, anything that gets you to study the kanji would work
