You do realize that you're suggesting a change that violates the license that HCL is distributed under?
b. Any Distribution of this Package, whether as a Modified Package or not, includes this file and is released under the terms of this Agreement. This clause is not dependent upon any measure of changes made to this
c. This Package, Modified Packages, and derivative works may not be sold or released under any paid license. Copying fees for the transport of this Package, support fees for installation or other services, and hosting
fees for hosting the Software may, however, be imposed.
(Emphasis added by me. )
The way the license is worded, future versions are merely Modified Packages of the originally licensed work, and must be similarly licensed, which prohibits use of a paid license.
