yes. There is already a "DrlDumper" that takes a Rule and dumps it to a string, using a bunch of recursive mvel templates.  You can copy/paste this and have it dump to CLP instead. 
https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/main/java/org/drools/compiler/lang/DrlDumper.java
https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/main/resources/org/drools/compiler/lang/drl.mvel

if you change the drl.mvel to a clp.mvel and change the text it outputs, you have yourself a CLP<->DRL translator. The caveat ofcourse is you must keep to the common base level of features between the two systems.

I'm confused, what's this to do with DRL and CLP?

Currently I'm under the opinion that good old CLIPS could theoretically be a common denominator to enable common rule definition, and partial execution of these on mobile devices.
