The K1 GBA seems to be a more or less perfect clone. With that in mind, would it perhaps be possible to use buttons and underlying rubber domes from a real GBA SP in it? In that case you could transplant those from a broken GBA, or just buy one of those repair kits, and hopefully make it work better. Or perhaps you could even swap the whole shell?
Just a thought, it seems like there are some button issues. If I was planning to get one of those K1:s, I'd test the theory myself, but perhaps there are other brave souls out there willing to test it?
