Ask yourself: what enjoyment would you really get from unpunched modules sitting in your closet?
You've spent a lot of time drafting HASL maps. Maybe take an actual art course. I'm not saying it because I think your artwork is bad. I'm saying to do it because you'll meet other people with similar interests, who will tend to be supportive and have positive things to say about your work. They would probably find your hobby at the least interesting, certainly unique to them. Best thing I did in the last few years was take some writing classes with the local literary society. It connected me to people, energized me, and encouraged me.
There are plenty of other things you could do with it - art supplies, decorate your flat, charity.
More boxes to sit in the closet? I'm not seeing it. Especially since you have shown a creative streak and a wide range of interests - how many times would you have to play OtO2 before it showed irredeemable signs of physical wear? And how likely are you to play it often enough to do it?
