Are you using the right description term here? Are the inserts really cupped, or just sunk? I understand cupped inserts are common in other makers EM's of this era, but I have rarely see a 70's Williams with cupped inserts. Sunken, yes, all of the time.

If this is the case, just remove the inserts with a heat gun or blow dryer and then reset with superglue gel and press flat. It will not take you too long to do and the results are very acceptable.

Watch this series of videos on youtube. 4 parts. I have had great success using this

I would like to add, I do not recommend filling with Polycrylic, it is my understanding that you have to wait almost 3 months for a true cure, then sand down the inserts flat. A lot of work that you already said your not ready for.

In these video's, this guy sands down the inserts, that's too much work and trouble and defaces your inserts. Just Novus 2 then 1 then inserts to a nice bright shine. If you do not want to go through all of the videos, just watch parts 1 and 4.

Here are the rest of the videos.

Yes, you have the correct understanding. GL
