All that will do is strengthen the link between those two chakras. Bear in mind though that the natural pair of the 6th chakra is the sacral chakra, it's only through using the king and queen meditation that one establishes a strong link between the 6th and the solar plexus chakra.
The quickest and most powerful way to stimulate and empower your chakras is using vibration, preferably during the hour of the day which rules that particular chakra ie vibrating RAUM or SURYAE into the solar plexus chakra during the planetary hour of the sun on any given day. Prior to this you can draw energy into the chakra and illuminate it as bright as you can and afterwards visualise it opening like a bright flower.
