"Tall" charasets? I assume you mean RTP-sized (the same size as the ones that RPG Maker came with). Those'll actually work.. Based on the size, anyway. (Though I guess the stool is a bit small. You can edit that directly in the charset without affecting much.)

Other than that, for various charsets/chipsets, check Google. If you can't find it there, it doesn't exist as far as the general "internet public" is concerned.. you'll have to, unfortunately, make your own.
