It can be done, I did it with my XL500, but it is tough to find the right parts. You need the module(that takes the place of the coil, looks similar but is called a module), the module bracket (its different from the points version), and the rotor (looks like a flywheel) from a saw that was built after about 1982. I tried a module with a points flywheel, no good. I could not figure out why but I suspect it is the timing of the magnets in the wheel.
D as the 1st or 2nd digit in the serial number would be 1982, anything with or after that should be electronic.
I found that getting the right parts on the bay was very difficult, the parts were either mis-labeled or inopp when they arrived. A trusted friend got me the right stuff from a parts saw that he knew sparked but did not run. I have SXL's with electronic and other saws with points, it seems to me that the electronic versions of the same saw consistently start easier.
I use spark plugs with the small iridium electrode in all my saws. I used to get them at a big box store but they quit carrying them. (https://www.amazon.com/Autolite-XST2554DP-Xtreme-Iridium-Garden/dp/B001O0A2BW , this is what they are, not a recommended source.) More expensive but again I believe they make starting easier.

These electronic ignition modules work too, if your just looking to eliminate the points and condenser and keep the coil. www.rotarycorp.com/product/8786 There are several different brands and price points; may or may not all be made from the same company. Seems most people have the best luck with the NOVA brand, I've installed one but don't have a lot time on it; so I don't know the longevity of it. Easy hook up.
