IF the Helicoil doesn't seem secure, move up to Timserts or similar. I would not go to a bigger bolt. I followed the timing belt cover debate while it was hot a few years back. I've been running them without the front covers for a long time now with no problems. I don't do anything crazy, like rally cross or bashing through snow drifts though. It is a lot easier to monitor condition and tension and idler bearings with them open.

Heli coils obviously worked fine , and there’s options too. In certain situations you may prefer something like I use - Timeserts. They are a bit pricey but you get what you pay for. That said you can also find simple heli coils on multi million dollar machinery. An insert allows you to bolt up and be able to remove that bold as well without any coil coming out with it. There are others but I found Timeserts to be great. Covers on , covers off - the great debate ! Lol I prefer they be on. Just spent good money on a couple New covers and seals because I expext longevity on our cars.
