At least from the start. It's just, I appreciate what runners here do, but for me half the fun of this game is trying to figure out what I can do with the given boons. I use Olympians' keepsakes sometimes when Duo boon is very possible, but not from the start, and I don't see myself grinding for a certain combination any time soon

So what do you think

If you join the discord (linked on this page), there is a formal process (recently added) for category suggestions. The details are fully listed in the relevant forum channels in there, but making a post that explains the category and links a video of a run would be a good starting point to making a category, as most of the community is more active on the discord than on these forums.

Personally, when I want to play like that, I play fresh file. It's a bit like playing booster draft tournaments in Magic rather than entering a more restrictive tournament format.

Your way is valid, though! It's just a matter of how many people share your interest in making it a speedrun category.
