Can flat paint and enamel paint be mixed?

can i mix latex with enamel paint?

I'm going to try it because of the definitions below. found at http://www.ehow.com/about_5104253_latex-enamel-paint.html

1. Latex Paint

2. Latex is, simply put, rubber. Whether natural or man-made, latex is the term used to refer to it. Latex paint is paint made with rubber mixed in as the binding agent which, when dry, holds the paint together.

Enamel Paint

The term enamel when used to describe paint refers to any kind of paint that is hard and glossy once it has dried. The easiest way to think of this is to think of the enamel that's found on the outermost layer of human teeth.

Combination

When these two attributes are combined, latex enamel paint brings the best of both worlds to the home. The latex bonding in the paint means that paint will dry quicker, is easy to use, and lacks much of the odor associated with older styles of paint. The enamel quality means that the paint will be hard, able to be scrubbed clean and will boast a shiny gloss.
