Personally I don't throw over 5 ounces with a spinner. I use a modified pendulum cast and can't hold braid with my finger, even with tape or guard over that weight. I learned how to throw conventional 30 years ago with an Abu 9000, and have never looked back. I feel this is a very user friendly reel for a beginner. I also believe that you will achieve overall more distance in the 6-10 range using a conv reel. Opinions on this site will vary and may be opposite to my experience.
I have converted a few rods, but they were usually an old build (10+ years old), with old glue holding the reel seat, or was lucky that the reel seats were large enough to allow ample clearance when cutting them off with a dremel.
You will need to replace the reel seat to spine the rod opposite of it's current orientation for a spinner. If you are not prepared to do that, I wouldn't make the change at all. This conversion also requires stripping the front grip and possibly moving the new reel seat further down on the blank, depending on set-up.
You will also end up stripping all the under wraps, because your spinning layout wont match, this will leave ugly remnants. Some of this can be buffed out with alcohol, or other, but it will still show and can kill resale value.
Also, if the guides were heavily epoxied, you risk slipping with your exacto blade and cutting the blank, which could blow up later, especially at the thin end of the blank on the smaller guides.
Best of luck with your project. Bravo
