I significantly doubt if what you're asking is easy or even possible.
However, you could use an alternative approach if you're using Maven to build your projects. We've used a setup where the Maven build compiles the LESS files into CSS, before putting them into CRX as part of the clientlib. So our clientlib is defined to use CSS files that don't technically exist until compilation, then Maven creates them. Both the LESS and CSS files are deployed to CRX, but the LESS files are really only there for informational purposes.
The drawback is that you can't make ad hoc changes to the LESS files within CRXDE (that isn't your primary IDE is it?), but I've found this limitation quite easy to work around. I really like this setup, because it gives you a bit more flexibility in how your app compiles and it works around a few other limitations of CQ's built-in LESS compilation.
