There are some Eastern scales that can be translated into Western notation and can be successful. In these instances, since the scales can be translated verbatim, the only insulting thing about using them would depend on your intent.
That said, there are many other scales with slight microtonal adjustments that don't conform to the equal-tempered system (such as your guitar, or a piano.) Therefore, it is the perception of the action of "shoe-horning" their culture / music through a Western Idiom that may come across as insulting.
If you are truly passionate then there are some ideas that can begin moving the ball along:
- Learn more about their music / culture
- Learn more about their music theory
- Learn about the limits of Western instruments
- Purchase / Build an Eastern instrument
- Modify a Western instrument
Microtonal guitars do exist, so just realize that without utilizing any instruments with microtonal capabilities, you will only be able to represent a small portion of Eastern music in your playing and writing.
Composers all the way back to Mozart have looked to the East for sounds and have used them to different degrees of success in their music.
