These chord voicings can also be used in tunes. Check out some Joe Henderson tunes like Black Narcissus and Inner Urge. These are extremely fun tunes to play that employ major7#11 chords all over the place. Joe is also a fantastic soloist. I suggest that you really check out his playing. Lift some of his lines, his ideas, his amazing use of sequences across entire progressions and his time feel. Transcribing instruments other than your own will give you a new perspective and ideas for material that may not be as apparent to you. For example if you play jazz guitar, you should be transcribing and lifting ideas from horn players or piano players. Get some horn player phrasing into your playing and some piano player harmonization ideas in there as well. I have listed some Joe Henderson resources below.
The Raw Material
Here are some voicings you can check out. Pick out a few that you like and try to integrate them into your playing. It is always a good idea to know what each note of the voicing is and functions. (ex. root, 3, #11, etc). Also work with the scale notes surrounding the chord. (On guitar, it is easy to visualize).
