Given that Silent Image is a first-level spell, I wouldn't think you could do anything with the Minor Illusion cantrip that would duplicate the effect of the higher-level spell.

Silent Image specifically lists "creature" as an option of what to produce:

You create the image of an object, a creature, or some other visible phenomenon that is no larger than a 15-foot cube.

Whereas, Minor Illusion does not:

You create a sound or an image of an object within range that lasts for the duration.

In addition Silent Image also allows you to move the illusion, and change it such that the movement seems natural (by appearing to walk, for example).

If you are allowed to create an image of a creature with Minor Illusion, it's not going to be very convincing - it can't move at all.

According to the description:

You create a sound or an image of an object within range that lasts for the duration. The illusion also ends if you dismiss it as an action or cast the spell again.

If you create a sound its volume can range from a whisper to a scream. It can be your voice, someone else's voice, a lion roaring, a drum beating or any other sound you choose. The sound continues unabated throughout the duration or you can make discreet sounds at different times before the spell ends.

If you create an image of an object such as a chair, muddy footprints or a small chest-it must be no larger then a 5 Foot cube. The image can't create sound, light, smell or any other sensory effect. Physical interaction with the object reveals it to be an illusion, because things can pass through it.

With this in mind - I would say no. Minor Illusion is very limited (e.g. static), and cannot produce any side effects (e.g. no light, or other sensory effects). I expect this also means the light would pass through the illusion, and that maintaining the same properties as the physical version of the object is beyond the scope of the illusion. This is mostly because its not actually a real object (e.g. it does not behave like a mirror), it only looks like one.
