Well even with your quite conservative calculations [1] you end up with a size that is absolutely reasonable and negligible in a 100MB footprint.

[1]: Realistically, you're never gonna have all 95 characters in all weights for all font size, so the actual number is going to much significantly lower than the theoretical envelope. In practice, there'll be a main (font,size), that will have all glyphs (and it's going to be more than 95 because of the ligatures) in normal weight and no italic, with a subset of the glyphs in the three other modes, most likely not evenly distributed between modes. Then you'll have additional fonts (for UI labels, titles, etc) that are going to have much less represented glyphs and almost no variations of weight or italic if at all. Obviously the font(s) used for titles in going to have a bigger budget relatively to the glyph sample size, because each one is bigger than your baseline "e"
