My advise to you is to stick with your Kung Fu and obtain your black belt. Not because you need it, but because it may make learning other arts easier. not to mention that when I switched instructors, i switched at Brown belt and felt like a white belt when i when to class with the new instructor.
And I also, know what you mean about getting bored with class and such, I used to be instructed by a sensi that was all about Olympic TKD Sparing. I got bored with sparing every class and gave up. Two years later i have found another sensi that is open to TKD and we also study Kyusho-Jitsu.
Also, yes it is ok to talk and learn from other instructors about techniques and other arts. Just remember to do it with respect to who ever is teaching you.
A good instructor is one that can teach you everything he/she knows. A great instructor encourages you to learn from someone else. An Awesome instructor will also learn from you. - Matt Reid (malanr)
But of course, if you find that Kung Fu gets boring then maybe you just haven't found the art that you were made for.
GL on finding yourself.
