You want Calibri 0.08" high and a pen width of 0.028"? Forget it.
If you have a bold TTF, why would you want a different pen width? Fonts are designed for specific legibility & use in mind. If you don't like the font pick another.
There used to be tweakable TTF fonts,
https://en.wikipedia.org/wiki/Multiple_master_fonts, though mainly used by font designers:
However, multiple master fonts proved unpopular in consumer-facing use due to the difficulty of writing (or rewriting) consumer desktop publishing applications to support them, and because font designers have generally preferred to release fonts in specific weights and styles, as font files that have been individually fine-tuned. However, the multiple master concept remains heavily used at font design studios, allowing designers to generate a range of weights and styles quickly and then optimise them individually.
