How do I soften the edges or a text solid?

I created a series of words using a brush stroke text. The lettering is 2" high and .06" thick. How do I soften the edges? I’ve tried Fillets, which would work up to a point and are way too time consuming. I would be happy to bulge the surface.

Do you want them softened front and back, or just on the front faces? Do you want the corners of the letters rounded as well?

I wanted to soften the front edges. However…it would be useful to have the capability to soften any face as well.
