No doubt there will be a chorus of disapproval for my suggestion, since ‘you can‘t go tampering with a developer’s code’ (even if they’ve sold you something that doesn’t work, and have now abandoned you), but I would attempt to fix the problem here. More specifically, I’d ask a friendly LLM to take a look at the code, and come up with a fix. I have various orphaned stacks that have been given a new lease of life, and had some major failings remedied, through some judicious hacks. (I’m not a Foundry user, but I‘d also add that all Foundry needs to be compatible with Stacks Pro is for somebody to port the theme, which is hardly a major undertaking.)
