Yes. One can use the Glyph Transformer which is available in the Professional Edition of Font Creator and in the 30 day free trial that you have presumably downloaded.
Sans Serif fonts are easier to transform than Serif fonts, and those with even strokes are easier than those with a high contrast between thick and thin strokes.
See my Tutorial on Working With Bold Transformations for some tips on how to correct problems you are likely to encounter.
Use the measuring tool to measure the weight of the vertical and horizontal strokes before deciding how much transformation is required.
Vertical and horizontal strokes will probably need different transformations.
There is no undo for glyph transformations. You can save time by selecting and copying all glyphs and pasting back if the results are unsatisfactory. Then adjust the values and try again.
If the fonts contain hinting information, this will be lost during transformations or any glyph editing. Hinting is especially important for the display of spindly fonts on screen. Even your bolder version may not look good at small sizes. However, hinting is not used when printing.
Be aware that all fonts are copyright and can be edited only for your own use in most cases.
