No, don't do this. What you are asking is how to be non-compliant with the spec. To quote from the 2.01 version of the spec:
This specification assumes the use of selectors (see
http://www.w3.org/TR/REC-CSS2/selector.html), cascade, and inheritance (see
http://www.w3.org/TR/CSS2/cascade.html) be consistent with the definitions in the CSS2 Specification. For example, the CSS2 Specification defines !important rules (see
http://www.w3.org/TR/CSS2/cascade.html#important-rules) to create a balance of power between author and user style sheets.
Use the cascade. No special effort required.
