I doubt it. If I understand everything correctly: Due to the nature of 
extensions - that they are deeply involved in the main application - 
combining an extension with Gnash, would require it to be released under 
the terms of the GNU GPL. Distributing the extension under any other 
license would either require 1) the interface used to communicate with 
Gnash is abstract/generic such that another application can implement it 
2) Gnash is released with an exception granting this permission (which 
it doesn't, AFAIK).

Gnash is distributed under the GNU GPL (Version 3 or later) by the way, 
not the GNU LGPL.

If unsure, I recommend reading the licenses (available online) 
themselves, and consulting a copyright lawyer.

If you wish to make your DRM code proprietary, implement it in the 
action script itself. This is possible because the license of the 
virtual machine (Gnash) is unrelated to the software running under it. 
Just like a literary work produced in LibreOffice isn't covered by 
LibreOffice's license.

Oh, and of course: http://www.defectivebydesign.org/ | The campaign to
